I generally follow the same pattern:
feeling overwhelmed > feeling unappreciated and/or taken advantage of > feeling resentful > sarcasm and/or ranting > snapping at any perceived slight > blowing up, scaring the crap out of myself and others > sinking into this dire mental state where nothing matters and I just want to burn every fucking thing to the ground.
I’ve gone through all of those multiple times in my life. It’s oddly cathartic, but also really toxic and damaging.
I can usually see it coming and diffuse it in the early two or three stages by spending time alone or doing some kind of self care (nap, get a haircut, walk, get a massage, etc.).
Now however,given circumstances, those options are limited.
