I’m having an existential obsession crisis right now. I’m in the bathroom at work freaking out. My head hurts and I feel crazy :( even tho I’m not hearing or seeing things. It’s been like this on and off all day.

Really bad theme right now is death, I keep thinking about how one day or at any moment my heart will stop my brain will stop & my memories & everything I know will all fade away. It is giving me so much anxiety I’m only 18, but I realize it all happens to us it is bound, we are born to die. I know it’s a silly thing to be scared because it’s not helping the quality of my life worrying about it and even when I do die, I won’t care , if you don’t have a working brain then how can you care 🤷‍♀️. It is tainting my everyday life currently & honestly making me terribly depressed & it is giving me derealization & making me feel nihilistic, I’ll remind myself it’s okay but then with my ocd i don’t stop thinking and thinking about it and it’s seriously so hard to stay present in the moment because this thought just feels like I can’t scrub it away it’s miserable I struggle with religion, but I do pray to anything that’s out there possibly listening, because it is comforting, it just feels like this whole experience Is pointless & I am afraid of the unknown and what is to possibly happen but I’m subjected to it anyways so why should it matter

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

Since I read that it's symptoms of schizophrenia voices in head who order to do bad things Usually I can deal with it but when I'm highly stressed I start to panic and idk if I believe voices and then I imagine living with it 24/7 it's horrible Im like it's unblerable part to feel pot in my stomach .. Am I in psychosis guys My psy is on vacation help ..I feel hopeless 🥺 Every time I read an symptoms on internet my mind manifest it but it's been a while my mind imitate voices because it's what scare me the most 🥺🥺🥺 A side note : I can attest that before reading symptoms it never even happened to me in my whole life
