Help!

I look back at various past events in my life where I said or did things that I feel really guilty, disgusted, and ashamed about. I replay them in my head for hours. I feel anxious about crossing paths with people that I've hurt or upset in the past or who perceive me badly, to the point that I will avoid going out in public as much as possible. I go out for work, errands, appointments, and occasionally to eat (even though those all give me a lot of anxiety), but I avoid community events where people might recognize me and I tend to isolate myself. The only people I see regularly are my boyfriend, my parents, and my coworkers. I live in a small community and I'm worried about people confronting me publicly and proving what a bad person I must be.

I shouldn’t have done this (trigger trigger trigger!!) So about a month ago..maybe I watched this video (as a compulsion to prove to myself) The video was called “interview with a p3d0” And basically it was what it says, I watched or more like listened to half of it…after I was disgusted by the person, but now all I can think of is every little thing I do, I feel as if tho I’m monitoring every thought/moment and feeling I have it’s torturous and I hate it..I feel disgusting, the person in the video has empathy and sympathy and had those feelings yk, I can’t explain it you’d have to watch the video yourself but please don’t it will ruin your journey…I feel more hopeless then before, my OCD is telling me so many things trying to convince me things that Ik aren’t true, I’m just really scared I don’t want to be that person I want to be a good cousin and person to my family, I’m sick of my head and myself, I’m so tired that sometimes I can’t even think straight, my head is always in pain and idek how to help myself..compulsions have been becoming more and more exhausting… I need advice or even someone to relate to, I understand I shouldn’t have done what I did but idk how to forget it.. I had made this post already but when someone replied I couldn’t see it for some reason so I’m uploading it again

I turned 20 years old today. Ive been reflecting a lot. Since ive joined this app ive been an ever changing person. Which is good i want to change i want to be good but i still feel the same inside. Especially when i feel like this. Feel of dread an anxiety. This sense of foreboding i hate. I just feel so sad. I didn’t have good teenage years. Ive just been sad since it began and now thats its over i dont know what to expect. Im scared. Im no longer a child im a full fledged adult. Everything feels so far away but everything still hurts. Im scared for my future but looking ahead at the same time. What do i do now that im 20? Do i drop my interests? Move out? I dont know i feel like i need to do something. I dont want to spiral but i feel so much dread. I dont know what to do.
