Being picked by teachers without me having put a hand up
P.E. + swimming lessons

(That being said, we don't really have high schools over here like in the US.)

Biblical Angel Wrestling Game.

Vince McMahon can be a demon aiming to ruin the whole of it with executive meddling.

I don't think so, at least not at the time it happened. I took parenting classes with adults and the closes thing to my age at those places were ppl in their 20's.

Reminds me of how everyone had to run a mile, which is something that I was incapable of doing safely.

As for me, I'll mention bullying here. There's another issue I had, but it's something I don't feel posting publicly on this forum.

Nice to see you went all through with it and didn't give up, I bet most would have just dump the child.

Okay, I admit they were more like Gridiron drills, but the man had all the hospitality of a drill Sargent.

The only place I've heard that term is "A Few Good Men", so even though it is very broadly in the same category, our orientation wasn't quite as severe ;)

I was quite lucky in my year, as there wasn't much of a social ladder in my year group either, nor really anyone that could truly be considered a bully (weirdly I can't say the same of the other year groups). The closest thing to a social ladder was age, as generally x-th graders didn't hang out with y-th graders if x!=y. That and hang-out spots: each year and each gender had its own spot, e.g 8th grade boys hung out under that tree, 10th grade girls in front of that class etc, and from each year to the next you rotated up in this series of locations.
Each morning we would meet in our spot, and every new arrival regardless of popularity would greet everyone already there with a firm handshake - naturally 2 or 3 boys took this as a show of strength and always tried to crush your hand xP

Is this question only to United Statians, or everyone in the whole wide world?

My main stressors in high school were:

1. Whether I can get to university for IT/telecom studies after the high school. I didn't at first try (I got to "machinery" and "construction building" department which just didn't interest me in the slightest, even if I was sure I could make a career out of them). I studied there one year (I remember learning how to draw some machinery schemas or whatever, and how to use CAD, LOL) and next year went to the entry exams again to the same university, and this time got to the "computer studies" that I was really interested in.

2. Where to find some attractive female as a girlfriend, or at least to have sex with. Still being a virgin in high school felt so stressing, as if I was the main protagonist of some stupid high school comedy movie, doing nasty things to apple pies etc.

3. The incoming military service, but for me that wasn't until one year after high school, but it still stressed me a bit even in high school.

4. Obtaining a driver's license. My father kept bugging me I should go to a driving school ASAP, but in the end I waited until I was 19 years old (ie. after the high school). My buddies at high school went to driving school already during the last year of high school, I didn't.

When I got to the driving school, I got the angriest and the most asshattest teacher of the whole school. God damn that old guy had some serious anger management issues, making even me nervous occasionally.

Like one time he suddenly shouted at my ear, why am I driving "too slowly"? I was puzzled what the hell is he on about, and then he was like "Oh, I saw the speedometer wrong as I was looking at it from an angle, forget what I said...". Yeah, whatever, asshat.

5. Forgot one: during the second year of high school, at least there used to be a custom that the second year class students attend a ballroom dancing party ("Vanhojen tanssit", meaning "The old people's dance party" or something like that), kind of celebrating that they will become the "oldest" students in the school after the third-year high school students start concentrating on their final exams.

So a bit like those high school graduation parties ("senior prom"?) in American movies like Carrie, except that we don't vote for the King and Queen of the party, and throw pig blood on them, which seems to be customary in US. Instead we dance in lines old folk's dances that we have rehearsed beforehand together, all dressed up like some fjucking royals.

Anyway, when the dancing rehearsals at the school were starting, everyone was supposed to participate, and everyone was supposed to find a suitable dancing partner. And then the teachers would join the odd couples, the leftovers. Naturally all the cool guys got the prettiest girls etc., if was all very hetero-normative, you needed to be proactive if you wanted a certain dancing partner etc. Of course it would be quite embarrassing if you would be without a dancing partner of the opposite sex.

Anyway, I was just lazy, I wasn't interested in the slightest participating in those dancing rehearsals. I just felt they were boring and waste of my precious (gaming) time. I didn't even try to find a partner, and then the teacher told me there is an free female student who would like to have me as a dancing partner. She was from another class and I didn't know her well, she was kinda shy and silent and "odd", I don't think we had ever said a word to each other.

I didn't really have anything against her, I just didn't want to participate to the dancing rehearsals (I think they were arranged after school, ie. at my free time), or even the whole party, if I just could avoid it. So I didn't.

Anyway, the teacher sometimes asked me about it and made it clear that girl is quite devastated because I don't seem to be interested in being her dancing partner, and yeah that did make me feel bad. I wish I could have told her it is not her fault, but me. I just don't want to dance because cool guys don't dance.

Who knows, if I had accepted that dancing invitation, maybe I could have gotten rid of one of my other stressors (virginity) already then, and she would have become my first true girlfriend (not counting the girl next door with whom I spent a lot of time when I was like 5-10 years old)? I will never know. Fortunately, I did get rid of it a few years later though, after which I became a real man and obtained my superpowers. I looked it up in Google Translate, just to make sure what it is (I guessed right).

You should too. Google is your friend, because only a true friend knows even your deepest secrets, like Google does.

Yeah, I've never seen this word before.
I asked Gamez he helped me out :P
Anyway as a good anti-telemetry I use DuckDuckGo.

I try to use it from time to time, and it just sucks. Apparently it uses the MS Bing search engine or whatever, but it seems to show irrelevant links much more often than Google, apparently the search engine isn't as advanced as that of Google.

As Google says, their search AI doesn't blindly show found matches, but tries to figure out what the user is most likely seeking for, based on their location, what people normally select from the links etc.

So if you e.g. search for "apple", Google will not show pictures of different apples or ways to make apple pies etc., but it guesses you are probably looking information about Apple products or the company, as that is what most folks are doing.

When I search for the meaning of some acronym, Google is much better in trying to figure it out, than DDG. DDG may give me some silly American organization names etc., while Google figures out it might be something more relevant to where I live.

true
i sometimes have to use google especially for hungarian stuff , way better for that than the duck

In my state you could go to a school which followed one of three syllabi: the state syllabus, national syllabus or another (international?) syllabus with school being education up to 18 years. I went to the state syllabus for both levels. In it, up to 10th grade / 15 years you had 10 subjects including 2 local language papers(Malayalam in my state's case), Hindi and the usual math, science, social science and English. For 11th and 12th grade you had fewer subjects based on your specialization and just one second language (besides English). Me having a hard time with math, chemistry, Malayalam and Hindi up to 10th grade, chose humanities(no math or chemistry, but also no biology or physics) for 11th and 12th grade with second language chosen to be Latin(no Hindi or Malayalam), with the desire to course through school on easy mode. Academically, it was easy but;

1.Our class-teacher(ie teacher responsible for mentoring / minding the class) chose another boy and I to be prefects and this put both of us in a dilemma about whether to ''side'' with the teachers and become a snitch or to side with the druggies in training who were the largest group in the class and ignore their scummy behavior.

2.It was an all boys school but I don't know if this had much to do with it but there was plenty of bullying, mostly verbal. At the time I ignored it since most people seem to have it like me or worse. I was bullied for being a prefect, for being fat and having really bad acne. Those who did not get verbally bullied were the gangs of druggies and instead they had physical fights outside the school. The so-called intellectually disabled students were the most picked on. To this day only one of the four ''disabled'' students seemed actually disabled to me with the others just seeming to be no different from the other students, almost all of whom weren't serious about class.

3.My class was full of other people who also got in to avoid math but most of them didn't have any academic interest (besides sports) whatsoever even in the easier subjects we had to study(which I was interested in). When the school had a youth festival and none of us volunteered to participate in anything, the class-teacher asked me to participate in some kind of essay writing competition and I won (probably because no one else in the entire school entered, I still don't know to this day). If you win at the school level, you have to go to the next level to compete and I had to do so and despite my class-teacher asking me to attend it, I pretended to be ignorant of the date of the next competition and skipped it since I was a social hermit. Later, he called me and said he really thought I would attend it and that it was a great opportunity and all. I didn't feel stressed but his disappointment made me feel disappointed in myself.

I could help you with that BUT I could NOT learn in that type of environment being TORN TO PIECES everyday wasn't fun!
My mother took me out because they (Italians and lebanese) were tearing holes in me the size of my fist as well as accusing me of being homosexual!
