*Forgiveness for a parallel drawn that may sound like whining/ bragging*
I can tolerate multiple inputs very well, to the extent that I need multiple inputs in certain cases for certain circuits to close. Don't have an excuse for it. I just know that creative or semi creative visual processes (laying out a roadway in CAD, painting, writing) require musical auditory input. Silence, crappy music, and people talking just make it worse, to the point that I can't think.
On the other hand, I know the limit of what I can handle well. Loud sudden noises make me either hit the deck or get halfway there before I catch myself. Loud prolonged noises (concerts, idiots that talk too loudly, most movie theatres), sudden movements, and sudden changes in light or really fast moving changes tend to bring out the worst in me. If Geek or certain friends that know about it are around and start seeing the warning signs, they know I need out and can't find out. (Warning signs are hyperventilating, eyes constantly moving and not focusing on any one thing, not hearing people talking because my auditory channels have shut down, and a few others.) Whoever it is essentially has to grab me by the hand or shoulder (Geek bodily picked me up in a fireman's carry a few times when it was really bad) and lead/ propel me out of the area. One of the worst times was in a planetarium for a light show. CS Guy didn't catch it until after the fact, when I had completely shut down (eyes closed, hands over ears, scrunched as far into the seat as I could get, and repeating "I'll be fine, I'll be fine, I'll be fine" under my breath.) He finally jostled me out of it by.. y'know I don't remember, I just know he fixed it.
Anyways, I only have an inkling of what you're going through, but that inkling makes me wish I could find some miracle cure.
