This has caused serious problems for me in regard to family, friends, and girlfriends. It has caused so much grief in my life that I too, like many that suffer this, have wished to be deaf at times to avoid the anguish.
I can not stress enough how much it affects me. I've tried in the past using rational understanding to retrain myself, but it didn't change anything. I think the only time that I'm not affected so much is when I'm drunk, which isn't often at all.
This guy in the video below describes exactly how it has been for me. I'm am extremely satisfied that I found that this is an actual condition and not just me being insane. This helps so much to know that I am not alone, even if there isn't a 'cure'. I really doubt anything could 'cure' this anyway.
I leave the room when people eat. If someone watches a movie and begins to make noises, I have to leave. If an actor makes noises, I have to mute.
