Tried weed at the weekend and I reacted absolutely terribly, I was screaming and crying thinking everyone except my boyfriend was the police and would physically shout SHUT UP FUCK OFF whenever I had an OCD thought...has anyone else experienced this? Is there something wrong with me?

I recently started medication as I have struggled with harm ocd. The thing is is that it’s not actually stopping the thoughts which I know is a given and it’s scaring me more without the anxiety (ruminating) and making me belive it’s possible. And I told this to my friend and she suggested anti psychotics This made me spiral because it made me think that I’m schizophrenia and no hate or judgment to people with schizophrenia it just scared me. I started worrying that I shouldn’t be around people and a horrible person ect I know reassurance is bad but I just need some advice bc I really don’t know what to do and I’m panicking

I was doing fine with my schizophrenia ocd (fear of developing schizophrenia/psychosis), mostly because I was obsessing on something else for a bit, but something caused it to come back. I was at work yesterday and checked out a customer, he didn’t know English very well and was very quiet. However, when he was leaving, he said “thank you” loudly while walking out and I told him to have a good night, but since I couldn’t see his face nor his mouth move, I worried that I hallucinated the whole thing and he in reality didn’t say anything while he was leaving. The voice that said it sounded a bit different, however it could’ve just been since I had only heard him talk quietly before. I’m still wondering if I hallucinated this and it freaks me out, causing my ocd to make me believe I’m developing schizophrenia/psychosis or losing my mind again. I also always read that the difference between those with schizophrenia/psychosis is those with OCD have insight and know their thoughts are crazy, but then that leads me down a spiral if what if I DONT think those thoughts are crazy? What if I actually believe them and become delusional/lack insight? So a statement that would be helpful otherwise made it worse for me. One night I had a panic attack super bad because I couldn’t convince myself I didn’t believe I was in a dream and hallucinating. Any advice on beating these constant thoughts and how to cope with it? :/

I don't know what to do anymore, the fear of psychosis and schizophrenia is so bad in so hyper aware of everything I hear and everything I see, I've always had eye floaters now I convince myself that it's really me hallucinating, I've always had tinnitus but now I'm convinced it means I'm going to go crazy soon, I can't sit in quiet because all I'm focusing on is what I'm hearing, and searching for any sounds I can't distinguish, when there's background noise I get so anxious if I think I heard something but im not sure I did or I'm just anxious, I'm terrified I'll start having delusions and sometimes my brain confuses some sounds for other sounds for example say I'm hyper focused and I breathe and my nose makes a whistling sound my mind interprets it as a scream and I freak out thinking I'm hallucinating only to focus closer and realize it's my own breathing, earlier I was so anxious that I couldnt tell if I had an intrusive thought or heard something, I don't know how to make it stop, I've been through this theme before I just forgot how hard it was I'm having a panic attack please help
