@Jrblovsky, my intrusive, loud tinnitus started in May of 2022. I wasn't aware of any sounds before that day. About a week earlier, I thought I had pink eye, but it turned out to be blood in my eye. The tinnitus was unbearable, even when my eyes were shut. I went to the doctor to get some gel for my eye, and then came the day of awakening to tinnitus, knowing immediately that I was not in a good place.
Two ER visits and ten hours later, I knew I wasn't going to get a pill the next day that would eliminate it. They gave me some Xanax that night to calm me down. I called my friends and family to say goodbye. They kept me overnight at my request. I didn't sleep, of course, but I was overjoyed to see my mom and brother the next morning. I had made it through the night.
For one year I tried to work, but eventually I became too depressed. The next two years were spent in major depression. That period was a constant fight just to live or do anything at all. I went months without showering, though I stayed reasonably clean since I wasn't doing much. Even the fan in the bathroom was too loud, so I only did what I absolutely had to.
At one point I had to replace part of our roof, which I struggled through. I didn't get it right, and it ended up leaking into the kitchen where the valley was. It was just one miserable experience after another.
In April of this year, I decided I wanted to work again and get out of bed. Spring had come, and I uncovered my windows, which had been covered with blankets. I started looking for a job. I had given up my own business, but I went back to work for six weeks before realizing my boss was a self-centered narcissist. So I gave it up, but I was back in the game and out of bed.
The loud, intrusive tinnitus took its toll on me. It took three years, but I finally habituated this past April. I don't pay attention to it anymore, even though it's still there. Coming out of depression, I was hit with the realization of "I'm alive." The struggle of forcing myself to do anything or go anywhere was over. It felt like a complete turnaround.
Now I stay very busy, which has been a critical element in ignoring the tinnitus. So yes, habituation is possible. I can attest to that. It took three years, but I'm living again in a bright world.
