Actually, one name for this is Misophonia. I have it too. The is are some things you can do about it, Google is your friend.

When you can, you can use earplugs, put small headset in your ear to muffle sound and/or use them to play comforting music. Frankly if it gets real bad, I often just leave the room. It is just too overwhelming. I believe an audiologist was actually the one who first mentioned the condition and, I believe she called it something like Selective Sound Sensitivity?

I've read that sometimes desensitization can often work. Stress definitely makes mine worse.

People swallowing, sipping (especially coffee in the morning) and clinking their fork against heir plate or making noise when they eat are real big triggers. Even in group, where we are not supposed to eat, some people do, and if it is really getting to me, I'm allowed to walk out for a while. In fact, this happened just last Friday. When I'm less stressed,it isn't as bad, but it is still there.

If something works for you, it would be great if you can post.
