I had basically the same problem, but was unable to adapt. I got my hearing aid when I was 17 or 18. Everything sounded tinny and harsh, and my hearing in my left ear is more or less normal.
I guess the bigger problem was that putting it in my ear made me very dizzy, but I'd have tried to deal with that if the sound weren't so bad.
