I rarely post in this forum but I stop in time to time. I (we) have all been where you are, scared, depressed and devastated. It sounds like your T came on suddenly with no known reason. I am in my second fight with T. The first one was 12 years ago after an hour of exposure to VERY loud noise. My T was a very loud piercing sound with ringing/hissing/humming fullness and pain. I was so devastated I lost my job and stayed in bed for 3 months with a sound machine to drown out the noise. But guess what, it SLOWLY faded away, and after about 18 months, it was totally gone. I don't mean I couldn't hear it anymore, I mean it faded away, gone.
I am now suffering a 2nd fight with T from going to an outdoor church concert from a local band about 6 months ago. I was always careful with loud noise and stayed out of the main speakers sound, dancing with my wife off to the side. Well, the last song (of course) it got loud, and 2 ladies about 6 feet from me decided to scream as loud as the could. That started my second fight with T. I have good days and bad days (mentally) but the T has faded a lot in 6 months.
I expect at least another 6 months for it to fade to the point I don't notice it, but I fully believe it will go completely away.
I don't believe your T is permanent, and will fade away over time. It just might take months, but I truly believe you will have your silence back.
