Hi Jason,
Sorry to hear you are going through this.
Back in March 2016, I was driving to work and it was a fairly warm morning 50+ so I drove with the window half open to work. I need to take a bridge to get to work and sometimes it gets backed up. So, I get stuck in the line to cross the bridge and suddenly, a car with a very loud motor whizzes by and my ear popped. It was so sudden because the car was headed in the same direction I was. Anyway, I went to work and did not make much of it. That night when I put my head down on the pillow and heard the hiss I hear now, I learned what tinnitus is. I also joined this site the next day and Googled till I couldn't Google anymore.
Like you, I went through a lot of self blame and asked "why me", "why couldn't I have been 5 minutes late or 5 minutes early" and basically went through the same feelings you did. Needless to say, it was difficult for the first 1-2 months. Then, I finally convinced myself that tinnitus is not a killer like cancer for example. Also, I am able to use my arms and legs. In essence, I stopped fighting it and as soon as that happened, it gradually released its grip on me. It no longer causes me anxiety and stress. Of course I hear it, but my mind just dismisses it as not important.
Again, I understand it is not easy and everyone has a different emotional/nervous system make up. I also know that everyone's situation is different and some people have very loud, deafening tinnitus. Anyway, at 37 you are younger than I (I'm 44) and we both still have a lot of life left to live.
There is a crazy election in the US, breathtaking world events occurring, technological change happening at break neck pace, and much more! It is a wonderful time to be alive. Also, we are now in the Fall season here on the East Coast with beautiful scenery. Enjoy life and leave tinnitus behind! It is not worth your time or effort!
