I have true empathy for what you going through, Enrique. It sounds too much like my struggle back then, with ultra high pitch loud T and severe hyperacusis, which caused my brain to sink into relentless anxiety and panic attacks. Each day was a long dark day of suffering. The tired and stressed out mind saw no way out and I was in deep depression with sleeplessness. Each night when I went to sleep, if I could sleep at all with sleeping pill, I didn't want to wake up again to repeat the torture cycle again. That was some darkest period of my life.
So I understand the tough struggle in the initial period of T. Never did I think I would recover and live an absolutely enjoyable life again. You see, during the initial trauma, the brain is functioning with the limbic system which aggravates the suffering. Which look much worse than it is. The brain is overwhelmed and tired, controlled by many distorted thoughts called cognitive distortions in CBT. We need to challenge these thoughts and don't let them ruin our mental stability. I bought a cheap paper-copy book called 'Feeling Good' by Dr Burns and read that many times. But this book is specifically CBT oriented for tinnitus sufferer:

You must prepare for the reality that the initial suffering will be hard and yet it is not going to be like that for the rest of your life. You must give it time for your brain to absorb in the new experience/sensation. Trying to stay positive even though it does seem like easy to do. Try to accept this initial stage of suffering without making catastrophic projection of the future. They call this Catastrophic Thinking in CBT, a cognitive distortion. Try to read up Dr. Nagler's Letter to a Tinnitus Sufferer and learn to challenge those distorted thoughts, to replace them with more realistic and hopefully positive ones, as is suggested in CBT treatment.
For me, during the darkest time, I just kept telling myself that if others can survive severe tinnitus (and hyperacusis for some), then I will learn from them how, and I can survive it too. I copy their success by reading up their success stories. But most importantly, I give myself enough time. If a tough person like Dr. Nagler took all that time to get better, why shouldn't I have patience about my own recovery? When we give ourselves enough time, and keep staying positive, try some alternative treatment like CBT, TRT etc., then eventually it will get better. It doesn't take a special person to get better. The success stories were written by people from all kinds of background. I was anxiety and panic prone before T & H. If I can recover, have faith that you can too. So give yourself some faith that you can get well too over time. Just don't lose heart easily. There is a lot of life ahead besides T. It will get better. Keep up the hope. Take care & God bless your recovery.
