Well you've come to a great place to start, that's for sure. It may be comforting to know that many of us have felt the same way you do now, being exhausted with the prospect of dealing with tinnitus for the rest of your life.
I myself have had it for 3 years. At first I felt like I'd rather die. That feeling would lessen each day as I realized how often I "forgot" that I had tinnitus.
For example, I'd be reading and 30 minutes later go, "Hey, I have tinnitus! But I forgot about it for 30 minutes!" Those moments are sacred.
I'd wager that most people, no matter how loud their tinnitus, go through moments when they are less aware of their tinnitus.
These moments will increase over time. Eventually, you'll go hours without being aware of it and this is where things become quite hopeful. You'll start to recognize all of the things you can still do with your life.
You'll start to feel fortunate that you haven't lost more.
This feeling will push you through to the days in which they create the cure.
There are many attempts in labs all over the world right now, so we may have one within the next 3 years (is my guess, based on current lab results).
So remain strong. It does get easier, though in the beginning it may seem a crushing weight.
You will overcome it. Just give it time friend
