Shmacky-McNuts: Believe it or not, doing something you like while you are in the middle of a life mess. Is not a good idea. Doing something you have no interest in, is more logical.
Bad things stick in your memory better, due to the intensity of the events. It is more uncommon to be so intensely happy the same way you can get angry. Following the logic of this, you, performing a task or keeping busy with things that dont matter to you, will actually be better for your mental state.
Why? Because the things you dont care about will be associated with the anger or upset. Instead of the things you actually enjoy. So 6 months later. You arent still fixated on the crap that upset you. Because you wont be doing the stuff you had no interest in.
example:
Lets say you eat something, that is your favorite food, while angry. Every time you eat that food in the future tense, you will be reminded of the upset.
Well in my experience this is not even remotely accurate, so I don't believe you
