Sitting with the anxiety rn I feel terrible and guilty

Tmi warning I was being intimate with my bf and I kept getting the name of someone else pop up, but I didn’t feel anxious. Afterwards, as much as I tried to delay confessing, I couldn’t help it. I confessed. My bf was fine he said I probably didn’t feel anxious because I’ve gotten used to the anxiety and it’s okay, it doesn’t define me any more than it would if I was anxious. A few minutes later, he got upset and said that the confession kinda ruined a blissful moment. I’m so upset that my head feels so turbulent I didn’t even notice it was a blissful moment for him and could’ve been for me. I feel so awful. I haven’t slept in a day, I can’t stop crying. My bf is afraid that because this specific name keeps popping up, it might mean something and he feels less than sometimes because of it. I know I shouldn’t have confessed but I felt so safe that it was like a dam broke loose. I feel so awful. What’s worse is that I’m still scared it means something, I’m scared that my boyfriend’s fear is right. He’s very understanding of OCD and how it manifests in me and everything, I think I just kinda messed up a sacred moment and I feel so much guilt and confusion and just horrendous. I’m not even fully anxious. I don’t know what to do. I apologized a lot but I feel like I don’t deserve him and so selfish

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 had a horrible thought and it was my own thought. I feel awful. Also my heart is racing all the time
