Shit, maybe you could get into the PIPE-505 trials. You sound like the perfect candidate tbh. I didn't realize your hearing loss was the biggest issue. What was the inciting incident? Viral infection?
In terms of regeneration, nothing should be outside of the window. It's true you don't want continued degeneration, though. In this way, I'd just view re-/degeneration as a straight spectrum, with no real "drop off" point. I can't empathize unfortunately because I'd rather be deaf in my left ear than have my tinnitus, but my hearing is otherwise excellent. Surely you have some coping mechanisms like gaming or art or something?
Look into nicotinamide riboside. People swear by it for preventing hearing loss. We have a thread here where some testify it to regenerate some hearing as well. Also I'd definitely start taking Acetyl L-Carnitine and I'd consider Lion's Mane and Astaxanthin.
So back in Summer of 2014, I went to some concerts about a week apart ( I don't regret this because I got to see my favorite band, and I would do it over again if I had the choice, honestly). Then after these concerts, I remember listening to one song on full blast in some earbuds shortly after. (I however regret this very much) I was very ignorant and downright dumb. I always think back to that moment as "The straw that broke the camel's back." Immediately following that I didn't notice any issues, no ringing, or anything. I do go see the a GP shortly after for some ear pain and that was it.
I want to add that for my entire life I have been a huge hypochondriac, I have had self-perceived issues with breathing, swallowing, and I even was convinced multiple times that I had brain injuries. These problems all went away once I forgot about them and became distracted with other things.
So after visiting the doctor, I began worrying about my hearing. I don't know if I really did have problems hearing or it was all in my head, as the other things were. I think this because for a short span after visiting the doctor I forgot about my hearing problems. I went a semester at community college enjoying life, conversating, going to parties and everything. But, I remember after that, the problems all came back. In 2015, I had a earpiece from work malfunction in my right ear with very loud static noise, and it caused immense anxiety for me. (At that time, the hearing issues were still on my mind.) I remember panicking and thinking, "That was an acoustic trauma, you now have tinnitus, there's no way you don't, that was so loud!" And welp, later that night I heard a ringing in that ear....I cried and was very emotional.
Soon after that incident, I enrolled in the AM-101 trials after coming on this site and finding out about it. It didn't help me unfortunately, and I never knew if I got placebo or not as I dropped out early. I know that a few months after, my ringing did go away but my hearing issues remained. I certainly don't attribute that to AM-101.
Since 2015 the hearing and tinnitus has come and gone. I again went with spans of time where I had no ringing or perceived hearing troubles. Even when I smoked weed, which caused huge spikes for me in time of tinnitus, there was nothing. I had many nights of hearing nothing, I slept just fine. Just this semester at University, I went a few months without any difficulty. I went axe throwing with this girl, and it was loud in there. (Music and people yelling) I remember not having any hearing trouble. I conversed with her and others without any issues. I feel like if I did, my mind would immediately go back to remembering my hearing troubles.
Fast forward to a week later (late January 2020), and I went out to a bar with friends. I certainly drank a lot, but still, I remember having no perceived issues. I woke up the next morning and I remembered that it was a bit loud in there, and I remembered standing somewhat near a speaker for about an hour, and I became worried. Then it all came back to me, the ringing came back and so did the hearing problems. I don't know if I actually did damage or I'm experiencing all of this because I remembered my hearing problems and became hyper-focused on them. Since then, I have been really struggling. (The stress of a new job and graduating college has probably added to this.)
I now think about these issues essentially every waking moment, and I am always so focused on what people are saying that even if I understand the words, I don't remember what the hell they said. I am having one hell of a time at this new job for sure. In the past, I think I was able to forget these issues because part of me believed it was all in my head, but now I am very certain it's real...there's no way my mind can cause such hearing problems, no way, it has to be real.
The only way in which I think it's still made-up is that music still sounds great, and the fact that all I do is think about my hearing, so part of me believes that I turned a natural ability (hearing) into something very conscious and manual (If that makes sense) and that's why I'm having difficulty. Every conversation that occurs around me I intensely try to tap into and listen, and when I miss words I become panicked. Maybe I just need to let it happen, but I can't get my mind off of it. Am I having trouble hearing because I actually have bad hearing? Or am I having trouble hearing because I can't stop worrying about my hearing...It's all driving me nuts. I almost want a diagnosis of hearing damage so I can maybe move on, but since I suspect I have Synaptopathy I can't get one!!
(Sorry for the extremely long post, but this is all of my history with hearing problems, and I kind of needed to vent)
