Ocd acting up or psychosis?

hi there, I'm an 18 year old girl just starting college.

I have never been "officially" diagnosed with OCD by a psychiatrist (because I've never seen one), but I do have all the symptoms and have seen therapists who have told me they believe that I have it in the past so for the sake of these details I'm just going to assume I have OCD

I've been scared lately that I might have some kind of psychosis though as well. All these things I'm going to describe have been long-lasting parts of my life

I have kind of had delusions that I could read minds for a while. There's been enough "coincidences" in my life that have led me to believe this. The thing is that I know i shouldn't believe it because it's irrational, but honestly I still do. The same goes for predicting the future and thinking that I might be some kind of historical important figure?? It doesn't make much sense but I've had thoughts like this for awhile.

I get super paranoid a lot. I won't eat any food that looks different because I feel like it's poisoned. I also don't like to walk behind cars in driveways because I feel like the driver is just waiting for me to get near them and then run me over

I can't deal with anyone walking behind me ESPECIALLY in stairwells or when it's just the 2 of us alone. I feel like they're going to murder me and I get really scared. I've even had thoughts of my roommate murdering me when I'm sleeping or something and I get freaked out.

I have really bad intrusive thoughts that sea with demons/satanism. I'm scared that I'm actually possessed or something or maybe I'm the antichrist.

Sometimes I will be perfectly fine and then I'll look around and all of a sudden feel EXTREMELY afraid. In my experience, this has only happened when I'm on my own, especially in the shower. I will look at the ceiling and idk imagine someone there? Whatever it is it makes me hyperventilate all of a sudden and come close to tears

I don't actually hear voices but sometimes my thoughts feel really loud and I feel like the people around me can hear them. There's also another voice in my head that yells at me for stuff. I guess it's my own thoughts but also kind of not. When I'm thinking something for myself casually I always think in first person saying "I." This other voice doesn't do that, it addresses me as "you" and is only negative. I don't know if it's some weird mental compulsion that has stemmed from my intrusive thoughts but it's always really angry and says stuff like "STOP RIGHT NOW" and "YOURE SO FUCKING STUPID YOURE AWFUL" and it just repeats over and over until it drowns whatever other thing there is out.

I don't really know what to do. I'm seeing a new therapist next week to talk about OCD but I don't know if I should bring all this up as well? It's really embarrassing honestly because I can recognize that i shouldn't believe all of it, yet I still do. I've never actually told anyone any of this.

My OCD has made me obsess about mental health issues in the past so I'm just wondering if this is a part of that? Or if I really might be dealing with some kind of psychosis. I don't want to bring it up with the therapist if I don't have to but if I should then I will

What do you think?
