I'm honestly going crazy. My brain will not stop. I'm even ruminating over if I can stop ruminating or not. I don't know how it's got this bad but I don't have therapy until next Thursday and I need advice on how to keep sane until then

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

I cannot for the life of me stop ruminating or checking how I feel about thoughts or focusing on thoughts or creating more thoughts. I feel like I’m losing my mind. I want to scream. I try not to ruminate about the thoughts, but trying not to just makes me think about them more. I try not to check, but somehow, I still check. I want to let a thought sit in the background, but the more I try not to focus on it, the more I end up focusing on it. I don’t want the thought to expand because that feels like engaging with it, but I can’t just stop it from expanding. It feels impossible. People keep saying I’m in control of my compulsions, and maybe that’s true for the physical ones. But when it comes to the mental compulsions, I swear I have no control. It feels like I’m missing something that everyone else seems to have, like there’s some tool they’re using that I don’t have. Controlling mental compulsions has never felt possible for me. I’m starting to fear them. And every time someone says I’m in control and can just choose not to do them, I end up beating myself up even more when they happen. Or when I *choose* I guess. I don’t know anymore. If this is my fault, if I’m responsible for this, then what does that make me? I feel like a monster. I am at my wits’ end. How am I supposed to control mental compulsions when it feels like they control me? I freak out when they happen. They don’t bring me relief, they just make me panic. I want it to stop so bad.

I can't even look at myself in the mirror. I've spent the morning crying, and I feel like I don't deserve to. I feel like I'm a horrible person or a... you know. I'm so sick of this. I'm just so tired of everything. I don't see my psychiatrist until two weeks from now. How am I going to make it till then? :( Even writing this post, I feel like I'm deceiving everyone and that I'm actually a monster. I'm so convinced of this right now. I don't know what to do. I was literally okay a few days ago. I don't even know what's real and what's not, like... I think I do? But everything is so distorted. I can't stop replaying memories trying to figure things out. I really need my psychiatrist right now. I feel like I need to confess, like I've been trying so hard not to, but every person I see, I just keep thinking about how badly I want to ask them if I'm a bad person or not, and that makes me feel worse. A good person wouldn't feel the need to ask that over and over again, would they? What if I'm just seeking validation because I can't accept that?
