I think with rapid cycling it feels useless to even try, everything feels like its triggering something different all the time, but it really does help to identify what you can control and what you cant control and how you'll deal with each.

I know that I can control my reactions to stress, I try to remove myself from situations to calm down, then communicate my feelings calmly and rationally. I know that I need to do things to relax every day consistently, whether I'm depressed or
manic, I'm always anxious.

Coping skills are important for anyone, mental health diagnosis or not. Positive Coping skills make life more bearable. For me when I'm manic, art soothes all the chaos and give my energy somewhere to go. When I'm depressed, doing things that comfort me like cooking, reading, or gentle exercise make me feel better and more active.
