I got it about ten years ago and it drove me absolutely insane for a few months until I just accepted that I would have it. Then a weird thing happened: my brain stopped paying attention to it. Now I mostly only hear it when I think to myself, “do I still have tinnitus?” and try to listen for it. It’s still there, I just don’t care anymore. I had no idea that even what you hear can be such a subjective experience until I went through this, but it makes sense. You do this all the time when you tune out ambient sounds and conversations to focus on something.
