How can I overcome tinnitus by my self?

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

Here is what I say to people: I wish I could make it stop. I really do. I also wish I could stop tinnitus. What is tinnitus, you may ask? Well, have you ever gone to a loud concert and after it had a ringing in your ears. Or, in movies when a loud explosion hears, first it is often muffled, and then there is a very loud ringing sound. Well, I have hear that sound for over 30 years. Turns out the medications I took as a kid for allergies and all the antibiotics I was on for Strep had a side effect for some people - tinnitus - that sound that I have heard every decade, year, month, day, hour, and second, for the past 30 years. I have learned to live with it. As I type this, it is REALLY loud, because I am paying attention to it. But, in a few minutes it will fade into the background, and, while I will hear it, I will not pay much attention to it, and therefore I will go on with my night. I will listen to music, practice my story for the MOTH radio hour, and work out. I will clean up the kitchen and load the dishwasher, and I will eventually get ready for bed. I will go to bed hearing that sound, and fall asleep for a few hours until tomorrow morning when I start the day all over again. I cannot make the sound stop. There is nothing to do for it - no surgery or medication. Just learning to live with it, and that is what I have done. It is the thing that I hate the most in my life, and, if granted three wishes, it would be the first thing to change. For now, as I have for 30 years, I will live with it, and I will ask you to live with your noises in your head - the thoughts, the images, and the urges, and we will practice together accepting that things are not always as we want them, but we can handle that. We got this.

For a while now, I've been having trouble concentrating... especially when studying... so I'd play the sound of rain or a forest or something similar to distract myself, and when I'd finish and turn it off... a pile of thoughts would come back to me as if they'd piled up on me!!! Anxiety, rituals... what should I do?
