Maybe it'll not go away but you'll be much less concerned about it. I got T from a indoor concert ~ 2 months ago and the first month was like hell. I had panic attacks, crying a lot, depressed, not talking to anyone. When i saw that my little girl was so sorry seeing me like this, i decided to resist this f**king downward spiral i was going into.
Right now, even though the T loudness did not change a lot, i do not freak out, and handling it in a much better way. It's ironic that the brain, which is responsible of increasing the gain to hear from the damaged cells thus creating the noise, is adapting to the sound, seeing that it's harmless and putting it into a lesser important bucket of sensory stimuli. Which means, if there is a more important sensory stimuli around, you'll not hear the T.
For your brain to be able to do this though, you need to stay calm. It's hard in the beginning, almost impossible to do, but it'll be like this. Try your best to stay calm, and not to obsess with T. Take anti-depressants and anti-anxiety meds if you need. Try to sleep as much as possible. Do not give up eating (avoid sugar though, it's guaranteed to give me loud T 5 minutes after eating sugar), take supplements and work out to get into a better physical shape. Even though the supplements are generally folly, they'll play as placebo and with the hopes of they'll help, they'll help.
Also, consider participating into AM101 if possible. It has a 3 months window of opportunity after onset.
Do not read disaster stories here and there, instead read all the success stories over and over, they'll help you believe that you're life is not over. It's guaranteed that you're thrown into this hell in the beginning and you'll get over it and you'll be better. There are support groups for T, joining them and seeing that the people are living good lives with T can help as well.
As the last thing, know that there are a lot of investigation and research going into T right now. I feel myself lucky, luckier than the people who got T, say 10 years before. In 5-10 years there'll be a cure for T. It's coming, just hold on until then.
