I remember hitting that point, too. I went from obsessively talking about it with family and friends, to not wanting to talk about it.
For it getting worse, that's always a fear but I realized that no matter what I do to prevent it, it could end up getting worse anyway due to a virus or eventually presbycusis.
I use hearing protection when appropriate, but decided to not worry anymore. Hypothetically, if it does get worse, I would be annoyed that I'd spent so much time and energy worrying about it and being miserable.
