I have Tinitus to, the day it started I was so down that I wanted to sell all my music gear. In the meanwhile ( 10 years later ) I don't even notice it anymore and start to worrie I might be dead. Playing music and even in a rock band helped me a lot to get through it and eventually even got used to it. The specialist back in the days told me that it will stay at the same level, it will never get more loud so for me it's oke since there is no cure for it.
