I would have to say my biggest problem is with certain sounds. Mainly certain people's voices. I don't know what it is about the voices though. It doesn't seem to matter if it's loud or soft, high pitched or low pitched, Male or Female, or if it's a person I like or dislike. Certain voices can cause me to go ballistic. I tense up, fists and teeth clench and I have punched walls over it. I'm completely fine if I avoid the voices. I can't watch some shows, such as David Letterman and Wheel of Fortune, because I can't handle Dave's and Pat's voices. I love football, but I can only watch certain ones. There's a few announcers I can not listen to. Problem is, my husband likes to watch David Letterman and all football games. He doesnt' understand that I can't handle these voices, he just thinks that I don't like them or I don't like what they said. I also have left a store I was shopping at, because I heard someone's voice that I couldn't handle.
Smells also bother me but not as much as the sounds do. Lights don't bother me too much either. I actually prefer Fluorescent light bulbs to regular ones. I dont' really know why, but they seem to have a calming effect on me.
