Thank you all! It is wonderful to know I am not alone in this. My Mom was always sensitive to eating sounds, so I thought it was just a learned thing for me. But, since I have other sensory issues, it is very likely to be misophonia. Yes, it is eating and breathing noises. I have trouble going to the movies because of the sounds of people eating (even heard over the loud movie). I used to want to punch my husband for breathing so loudly when I was trying to sleep (He has lost 90 pounds over the last year and now does not breathe as loudly, so it is better, but not gone).
What helps me is not being around someone else who is eating when I am not eating. Unfortunately, eating every time someone else eats around me is not good for my weight. But, I have to get popcorn at the movie theater even if I am not hungry so that I am eating to help block out some of the noise of other people eating.
One of the other hard ones for me is that chewing gum is very helpful for my AS son, but hearing him chew it drives me completely crazy. It is a hard balancing act.
I find it interesting that with misophonia, the noise that a friend or family member makes is more irritating than a stranger.
