My world is falling apart

A specific obsession I have is that I’m convinced I have no future, I’ll do or say something within the next week or month or year that will completely ruin my life, I constantly have this sense of impending doom, every single second of every single day.

I’ll do or say something innocent or on accident and I’ll immediately feel my world crumble around me like “this is it, my life is ruined, that was what did it.”

I could be having the best day ever, and then my hand accidentally touched a strangers clothes while walking down the street and that will immediately trigger that spiral.

It’s making me so depressed, I feel like I can’t do anytbing without being triggered, not even online or with my close friends, I can’t do anything.
