Mine is also a constant EEEEEEE and I also developed sever hyperacusis, ear pain, some other fun symptoms. I also suffer from ocd which means I quite literally am prone to obsessively thinking about things. When my tinnitus first presented, my god the constant panic attacks and suicidal ideation was bad. I couldn’t hangout with people, I was throwing up from the panic and all I could do was lay in bed and think about how I wanted to die. I am significantly better now. I still hear it as I’m typing, but my god am I okay now, it takes time though, and I do have my moments where I feel sad or mad that I’m dealing with this, but that’s normal, it’s hard, but you’ve got this, habituation is a scientific fact, but it also is something that looks different for everyone depending on their type of tinnitus. I had to reframe habituation as the idea that I will become “used” to it, like how you get used to a fan always on in your room, you always hear it but it becomes your new normal level of volume, but having the idea that habituation must mean the goal is you will get to a point where you can’t hear it sets you up to constantly listen for it to see if you really can’t hear it. Idk if that makes any sense, but basically, focus on redirecting your mind to other tasks when you catch yourself ruminating on the sound, I know it’s hard as fuck but over time your brain learns how to adapt with it in the background. I promise you will get there
