Dear susan......I'm afraid I don't have any good news to give you.. I've been through severe tinnitus and hyperacusis, and I can understand every thing you are going through.. It is a hellish nightmare, and it took me in to the deepest depression possible for several years.. You try every method you can think of or find....and it always ends up the same way: It never cures it.. There is no medical cure for it, not yet any way.. The way I got it though is I was very stupid and listened to very loud music via headphones for too many years.. And then about a year after the tinnitus started, I was at some extremely loud party, and it made my tinnitus very much worse, permanently, and made my ears insanely sensitive.. I have to wear ear-plugs to even go in to a restaurant now.. I always have to wear hearing protection in lots of situations, or just cover my ears with my hands if I don't have ear-plugs..
There is a 15-minute-long video about some dutch woman who had tinnitus and hyperacusis, you can find it by searching the internet for "I have tinnitus and I want to die".. You will know it is the right one if you see her speaking dutch.. She eventually took her own life because she couldn't handle it any more.. And guess what, I plan on catching the train straight to hell my self.. I was always very happy, until this happened 7 years ago....And at first I was hoping it would just go away too.....I couldn't stand living with it...I first would tell my self "if these sounds don't go away in a month i will ctb".....then i gave my self 3 months.....then 6 months..then a year....Although what DID happen was I eventually habituated to the sounds......I didn't think it was ever possible to get used to the sounds...and it takes a long time.......So, the sounds don't bother me any more, but what DOES bother me is the hyperacusis...I am tired of protecting my ears all the time, but also, I can't even listen to music any more for more than like a minute....I can't watch anime any more like I used to...Even at low volumes, for some reason constant noise for too long start making my ears ring louder, and when they start ringing too loud, the sound DOES start to bother me.. I am a crippled person really because I can't function in society like a normal person any more.. Oh yeah and when I play video games, I have to play it on complete mute unless it is a game that lets me turn off the music.. I am tired of living this way....And since this happened 7 years ago, I have never been able to be happy since like I used to be.. I think 7 years is long enough to see if I could be happy again, and at some point you just realize...I'm never going to be happy again.. I think the method I would hypothetically use when I leave either this year or next year would be the helium tank...that just seems so cheap and easy and painless and quick..
And I wish I had better news for you.. But I don't think any one should continually suffer for the rest of their lives if there is no hope in sight.. For you and I, it seems like this isn't a temporary problem at all.. The only thing I can think of would be to decide if you want to wait even longer to see if you habituate to the sound or not....It took me about 2 years to habituate to it.....but I still have to protect my ears all the time so that the sound doesn't get worse/louder..
