PeteJ's problem is the combination of bad tinnitus with hyperacusis.
When you get tinnitus, you need motivation to continue your life. The worse the tinnitus, the more motivation is needed. The biggest motivation for those with severe tinnitus seems to be helping other people (Hazel, Markku, Dr. Nagler, Glynis, Fishbone, Jazzer and everybody I forgot to mention, they all seem to live mainly for others). When I had dark thoughts when I got my initial tinnitus, I told myself that I have to life for others, since I didn't see a reason to life for myself anymore. Maybe this is an evolutionary thing, because we might be realizing somehow that investing in our own lives does little for our tribe, but investing in others would be far more beneficial for the collective good (and thus for survival). So there is a reason/purpose to continue. I know multiple people with loud tinnitus (or moderate but with hearing loss) and they all seem helpful and humble people. Egoism doesn't seem a good reason to stay alive for us or at least not for a long-term problem. This ironically also applies to myself: now that I'm worse again, I'm trying to help as much as possible again (definitely no saint here).
So loud tinnitus is a condition you can possibly life with or at least stay alive, but if it is complicated by hyperacusis, then many of those options that would motivate you to continue your life are not possible anymore. We need to be able to get feedback from our peers that our live is worthwhile and we are helping them, that it is appreciated. That is - in my opinion - why PeteJ's needs face to face talks with people because it gives a feeling of belonging and purpose. Artificial communication over the internet may not be enough. The only thing I can think of to solve PeteJ's problem is another person who has about the same symptoms, so they can live for each other. I am not proposing a livelong solution, it is to hold out until there's a treatment on the market.
