Hi, there has been an useful topic on ag forum recently, created by someone who is struggling with the same condition as you.
I'm also one of those people and I didn't know there are so many of us lol.
Technology, medicine is advancing. The good and bad thing depending how you look at it is that you don't know how much you will lose, meaning frequency and volume wise.
There are quite powerful hearing aids and in extreme cases cochlear implants, so it is not the end of the world, if you do lose a significant amount.
I don't wanna marginalise your fears, because I am battling depression exactly because I found out what this condition is and how it affects me, but the worst thing we can do is stop engaging in hobbies, social lives, and think about this and nothing else, which is basically what seems to happen to me in my worse phases of depression.
I wish you all the best. Scientists are actively researching therapy, farmacology and such that can help us. It's not easy, but you deserve to have a nice, satisfying life without it dreaining you. Try not to think too much of it until it gets worse, if it does. There is no clear answer here, but you can actually use this to give yourself hope, not to fear. As far as I know, most of us don't lose our hearing completely anyway.
