I always thought my hypersensitivity was related to my migraines but it also seems to be related to hypo mania and depression too. Strangely I'm legally deaf when the TV is on it is lower than most hearing people have it and yep I always mute those commercials or just use close captioning and no sound. The good thing though is I can just not wear my hearing aids when it is bad. The smells and sensory stuff is harder to control. I can't stand showers, it feels like thousands of needles.
My reactions can be either jumpy or irritable or both.
I too am really glad to see I'm not alone with this problem.
