This is really sad news, though hopefully you can still get joy from creating in other genres, and I am sure your very obvious talent will help with that!
I know all too well the pain hearing loss causes. I have acute hearing loss in both ears and am totally reliant on hearing aids, and suffer from tinnitus. I discovered it at around 18 and it is slowly deteriorating-there is nothing they can do, although I have been lucky that the advances in hearing aid tech are currently keeping pace with the decline.
It does make it a unique challenge for a musician, though hopefully as you adapt to the change (if it doesn’t get better, which I hope it will) then you will learn to trust what you can hear and adapt accordingly. Your talent is obvious so you will overcome this.
I’ll never be able to make and mix music to a level of many people here (and my hearing is only partly to blame for that!!) but I still find ways to enjoy what I produce, and I sincerely hope others in the same boat can do the same.
For me music is an escape from having to deal with constant conversations-that is a real challenge with hearing loss as I just can’t keep up most of the time-at least my instruments talk to me in the way I want them to!!
I really hope you recover soon, all the best. Bloody covid.
