Is it possible to have ROCD about friendships? And what differentiates ROCD from social anxiety or FOMO?

Heyy so has anybody ever experience in rocd like ur scared that what if u liked somebody else or had a crush on somebody else even tho u never had no romantic or sexual feelings for anybody else only ur bf but u still question urself?

My best friend hasn’t spoken to me in months. It triggered some symptoms that I now realize fall along the lines of ROCD. It’s making me behave in a way that chased my other friends away. I’m feeling very hopeless and guilty.

My trauma has always prevented me from pursuing a romantic relationship, I’ve always been super terrified of pursuing something with someone for just about every reason I could conjure up. Now, I’ve met someone and I’ve tried so, so hard to push away all those anxieties to make it work; but I feel like the more involved I get, I become more scared and I dwell on more things that may be signs that our “relationship” should end. I keep thinking over and over that I’m not good enough for them, I might be their “target,” they’re not right for me, our feelings are not mutual, it couldn’t work out between us, my friends and family would not approve, I’m not ready for it, etc. Recently, I tried to break things off with them because they were too tall for me. I started sobbing because I was scared that I was being and awful person and I had completely screwed everything up between us. I wanna know if this sounds like ROCD ? I always had a hunch that I could have, but I had never gotten far enough into a relationship to find out. Please feel free to ask me any clarifying questions. Right now I’m probably not making much sense haha.
