Did i or didn't i do something?

I have made multiple mistakes in my past that lead me to believe im a bad person. thinking about them often sends me into a panic attack. i cant help but feel i need to be punished. i hate this feeling, what should i do?

im going to be vague here, but basically i did something in the past that i regret and it became a huge point of my OCD but i have talked to my therapist and i have mostly moved past it. i watched a video by an OCD youtuber that really put it into perspective. anyway, i have been with minimal worry for a few days, but now im having worries related to i think false memory? basically it’s like “oh but what if i said/ did this and just forgot that means i harmed this person im a bad person”. to me it sounds like textbook OCD but im just wondering if anyone else has experienced false memory / real event at the same time. i have a really horrible memory which is making it even more stressful. any responses are appreciated!

Does anyone else ever feel like they don’t feel “bad enough” to have OCD, or that they don’t feel “the right way” for it? Or like they’re just saying they have OCD as an excuse? Because i was so much better for like 3 weeks now and now im on my period and i started doubting again. So because of that im scared that i was feeling to good and that my fear is actually true.
