Starting to get thoughts like what if nothing is real again :( also feeling like I’m floating

I’m constantly thinking about what if I go crazy.No matter how good I’m feeling the thought always creeps back in same with what if no one is real.I used to get anxiety from it but I don’t really get it anymore as much which scares me.How long did this last for anyone who experienced this?I feel like it’s been going on for months and I’m scared it’ll never go away.

Is there something wrong with me if I’m not disgusted by my intrusive thoughts anymore like the disgust feeling has been gone for months now and why are my thoughts feel like they’re literally so close happening inside my brain why can I lowkey physically feel the images of that makes sense,Why do I get adrenaline why do I get a weird tingle my lips sometimes make an awkward like position when I get the thoughts it’s like I’m having a glitch idek which thought is intentional which one is intrusive but there bad thoughts and I don’t want them to be the truth about me but I literally cannot get myself to just feel relaxed even if they’re present like I actually get genuine headaches and feel uneasy for hours after having intrusive thoughts and I hate how it’s always the same kinda thoughts and sensations feelings etc around those thoughts out of nowhere when I’m just chilling they come in before when I had it is be like okay ew weird thought now I’m like what if I actually like this and I’m in denial uGHHH HATE MY BRAIN

Idk what to do anymore. I had an attack from 🍃 in 2021. I couldn’t feel anything and it all felt odd. It’s been 4 years! 4 years!!!! And I still have attacks. But in the past 2 years it hasn’t been anything visual really. I can see everyone, I just can’t feel connected to me still nor my surroundings. My head keeps repeating. “You’re not real, nothings real”. Even tho ik I can see my mom and dad and nothings distorted. I don’t get it! I’m scared. Is this the start of psychosis? I was diagnosed with ocd when I was 13 and it got really bad after smoking once. I feel alone. I know where I am. But I feel out of place, and for some reason I keep thinking nothings real in my head over and over again. I feel so alone. I want to be a nurse but I’m like I’m useless. Nothing feels right. Can anybody help me, or has anyone experienced this!
