Welcome sponda. Like you, I have really high pitch shrill in my ears starting a few years back. Mine is a high-energy dog whistle which can cut through many loud sounds. I can hear my T above the raging rapids around me while fishing, and above the sounds of the jet noise in my last 2 flights. In the beginning, it was very annoying. Not just annoying, my T literally turned me in a mess mentally & physically. Worse, severe hyperacusis (H) also hit me soon after T. It turned all normal sounds glassy and piercingly hurtful. So ya, T & H triggered relentless anxiety and panic attacks too for me on auto mode. So it was suffering to the utmost. I had to survive on meds initially. But like you, I found the online support forums so helpful, because there I found people who understand me and it is comforting to know that many survive sever T & H too and are living normal life. It gave me lot of hope back then. It makes the T journey so much better. I hope you will explore the TT site and interact with people who understand what you are going through. Do read up the success stories to give you hope that you can be better too like them over time. God bless.
