18F I think I’m going insane (PSYCH)

I don’t know what to do. A month ago I suddenly had a psychological crash, insane paranoia, a feeling that something is in my room, I think I saw bugs flying. My blood pressure dropped insanely fast, and recovered after 5 minutes, I was shaking and crying and didn’t know what to do. After that night I’ve been having that paranoia every single night. Dissociation, paranoia, I never actually saw anything, but I can just feel something, it’s driving me mad.

During the day I have extreme anxiety about my teeth (mind you, started a month ago as well), I think my teeth are moving and gonna fall out, that my bite is weird, every single waking moment. I went to the dentist, everything was fine.

I went to a psychiatrist. I got prescribed risperidone 0.5mg, but it didn’t help and I went on 1mg. It helped BUT my prolactin rised insanely fast (a common side effect). I went back to 0.5mg and it does help, but lasts shorter and anxiety is worse during the day. Now, I know that risperidone blocks dopamine, and dopamine could be the thing that causes my symptoms, but why all of a sudden?

Another thing, I have very random BP drops (down to 80 over 50, in 5 mins it rises to 90 and 60 and my normal is about 100-110 over 60-70), I often faint, or collapse. That’s weird, and I have been having nausea, unexplained weight loss and a growth spurt over the course of 7 months. My MD said that nausea is just all stress and honestly I just gave up. She also denied that I have those BP drops, so IDK I know I’m not blind.

I’m sorry for the info drop, but my psychiatrist refused to tell me what’s wrong. I’m a mess, I cannot rest, I’m becoming impulsive and mood swings are awful. Thank you to anyone who replies with atleast something.
