Ocd

I'm having awful stomach pain and nausea and it's really worrying me and scaring me

Medication for OCD? Hello all, 19 male here, this seems like a cool community that isn’t nearly as triggering as reddit. I have pretty severe bouts of existential thinking or fear of going crazy ( psychosis ) after some pretty heavy mushroom trips a few years ago, I know logically I should be fine but I do know what it’s like to lose it and it’s scary. Currently I deal with relationship focused OCD, it’s all day from before I even open my eyes. I want things to work out with my girlfriend badly. Also I can come close to a panic attack sometimes which perpetuates everything. Anyway, I mention the fear of going crazy because the way my anxiety/derealization makes me feel is that I’m not mentally stable cause I feel out of it or unreal. I saw that a lot of anxiety and depression medication can cause psychosis and I feel like I could use some help in getting ahead of my OCD because the compulsions are had not to give into when I’m in such distress/not knowing. Plus overall I just feel like I have no idea how I feel about close to anything. Anyone relate about that ?

I feel like the worst kind of person and I am ruining my husband. I don’t know how I’m going to be able to change.
