Unhealthy coping mechanism: take a break, put in headphones, put on the most overstimulating sad/manic/violent vocaloid music, proceed to engage in megalomaniacal fantasies of battle, world domination, and self destruction until you get bored.

Healthier coping method: try to do mindfulness meditations. Doing them even when you’re feeling more normal will make it easier to try when you are. Just trying to take a few deep breaths or focus on breathing could help and at the very least won’t hurt.

Another thing is just venting to someone or writing in like a journal. If something is getting to me or I’m feeling an emotion for no reason and it’s frustrating, venting about it in my journal seems to help me calm down and manage it better.

This is too general of a question imo. The answer won't be of much help.

But in general: getting rid of whatever causes the unwanted emotions, understanding that most causes aren't actually a big deal, mindfulness meditation, slow conscious breathing, practicing to control/let go of emotions, accepting the emotions itself as not a problem aaand yeah that's enough for now

To what extent would you suggest people are related? Do you feel like if people were subtracted it would be much easier for you to maintain a decent state?
