How do I stop feeling terrible and like a disgusting person because of my past mistakes? (none of them have to do with my ocd themes but I just keep feeling terrible)

I am in this same boat unfortunately … my past is making up stories too…

Sounds bit like real events ocd. I suggest being patient and kind to yourself during recovery. It could be good to make a script of a particular event that youve been ruminating on but make it into the worst case scenario of what you could've done, and read it over and over until it bores you :). Sit with the guilt, recognize where it is coming from in your body, and say "I feel what you're trying to do to me OCD, I will acknowledge the feeling, forgive myself, and let it pass"

i’m having the same problem:(

I also have this problem but it has to do with my ocd theme
