Relax dude, just don't be in very loud places and most importantly don't think about it.
Trust me I have only had mine for 1 and a half months and it has gone from a loud ring to loud static to mid static to what is now extremely low barely noticeable air sound that isn't even annoying in the least.
I don't have a history of damage to my ears noise wise, no concerts or gigs or discos or anything, there is a really good chance that it will fade as it does for a good amount of people who get it from concerts especially if this is the first time you have it.
For some it's a day a week a month for some even a year but it'll probably go away.
Mine changes as I notice it when I focus on it it starts being loud when I'm playing games or something I can't even hear it.
Just relax do the stuff you like and keep your mind relaxed.
Also try and not search anything on the internet also while this forum is quite supportive and has helped me in a big way I don't recommend spending too much time here as most people who post online are bothered by their Tinnitus, millions of people have it (most of them from random reasons don't get scared that yours won't go) and you don't see millions of people on this forum do you?
Keep cool and rest assured you have a good chance of it going away.
Might go tomorrow or the next month or even next year.
Even if it is probably temporary try and accept it, don't think about it and you will see it get lower and lower until it's just some sound you hear that doesn't interest you in the least bit.
If you're having troubles talk to someone, train, rant if you like I find a good rant really makes me feel better.
If you have any more questions just ask lots of people here have gone through what you have including me and almost all of the people here have had theirs go low and or have habituated to it and are no longer even bothered enough to listen for it.
