Too Loud, Too Bright, Too Fast, Too Tight is a very interesting book about sensory defensiveness-- having trouble, sometimes serious trouble, with sensory experiences that don't bother most people. It's correlated with autism, but isn't the same thing, and is sometime misdiagnosed as autism, neuroticism, or lack of willpower.

There are people who specialize in helping with sensory defensiveness. They are cleverly camouflaged as occupational therapists, so they are unlikely to be found.
