I'm sorry for your loss. I agree with everything you said but at the same time i feel it's my only choice. I tried everything in the book only for things to get worse and for physical problems some debillitating to occur out of nowhere for no good reason that explains them. I know it's egotistical to do that but I wish I had another choice, I really do.
I don't want to take my life, but i just want the suffering to stop. I wish there was some sort of help let alone treatments or cures. I'm at a point where there is no point in suffering, besides that my parents don't want to deal with this anymore although I know they mean well and if I were them I wouldn't want to deal with someone else close to me that was going through this as everything they tried in order to help me better my situation failed.
I never asked for all of this as well, I really really wish there were other choices for me out there. When I leave this hell I can at least know that I've tried everything in order to get better and in the end it's not a choice I made but was forced to (as much as it sounds like im shifting the blame but that's my view of it).
It's easy to fall into a victim mentality. I would know because I had it in the early stages of my catastrophic hyperacusis and I also saw it in my dad. I still have it, to some extent. I know people have mixed views about him, but Jordan Peterson is right when he says life is suffering. This thing isn't supposed to be fucking easy and for some of us it is god damn harder than others. None of us here asked for what we're each individually going through. Do you know how I get through each day? Knowing that there are other members on here worse than I am who are still managing to get through it.
After reading your post, I decided to go through your post history. It seems to me you have chronic tinnitus, hyperacusis and some kind of distortion issue (which usually goes hand in hand with hyperacusis). You've had an ABR, MRI and CT brain scan, all showing nothing, suggesting then that the issue may be peripheral. Your post history suggests you've tried one drug ONLY and no other supplement. Is that true? If so, I don't really count that as trying everything.
You've also said you have other health issues but haven't said what they are. It could be very useful to members here if you explained what those are. You also seem to be giving too much credit to your doctors: "my doctors can't help me, so I'm just going to give up". If you read enough, you would know that doctors are far behind the research curve. So on that note, please tell me what medical journals you've read. I don't say this in a patronising way, but sometimes it can really help someone's mental state if they can understand what may be going on from a pathology point of view, even if there's no current cure or treatment.
Please make a list of every drug and supplement you've tried. There are many that have helped others on here.
Please tell me what surgical options you've explored. For hyperacusis, the Silverstein surgery now has an 80% success rate.
Please tell me what other diagnostic options you've explored. You said you had an MRI for your brain. Did you have one for an acoustic neuroma?
Please tell me what alternative medicine you've tried.
Please tell me what medical journals you've read. Please tell me your current understanding of hyperacusis pathology.
Please tell me how many threads you've been through exploring what has helped others.
I see so many people on here who just say "the doctors can't help me, I give up", as if to say that just because a doctor can't help, nobody can. Do you know how many other diseases and conditions are out there that doctors can't treat? People have to resort to helping themselves all the time. Just because doctors don't have an answer for you doesn't mean there isn't an answer to be found. For example, if you speak to any ENT or audiologist about type II afferent fibre sensitisation theory due to OHC ATP leakage, they will give you a blank stare, and yet this model is becoming largely accepted in the research community as a model for at least some types of hyperacusis.
Let me put it this way to you. Let's say there is some kind of afterlife, but which isn't as good as life is here. What if you found out there that there was some information out there that had you stumbled across, it would have changed or at least improved your condition enough to give you some degree of normality? I bet you'd regret it.
Edit: One other thing. I can already see you downplaying the effect your suicide would have on your parents, as if they would be better off. Who are you to gatekeep the effect this would have on your parents? I can tell you from now they would be devastated. You don't believe me? My dad's mother died a week after my dad took his own life. I urge you to think again.
