Struggling with OCD and Relationship Intrusive Thoughts

I’m 22F and I’m really suffering but it’s probably my fault. I developed an OCD theme about me cheating. I will obsess about this game I played for a while it’s a virtual game and essentially you buy clothes etc post photos whatever. It’s fun and I don’t leave my house because of panic attacks. But then I started obsessing about cheating because people would name servers random names. My bf does not think it’s cheating neither do I. I also got intrusive thoughts about a male friend so I stopped talking to the opposite sex socially period. And I even isolated myself from women because I would get thoughts. I’ve self-harmed over the fact I’m a cheater or could be. And I’ve made suicide threats and attempted to break up with boyfriend. I’m trying medication soon
