Only now, after many years of therapy, has my own research brought me to hear of Sensory Sensitivity. Finally! I have a terrible time with noise, bright lights, bright colors, and too many people. I am totally unable to multi-task. As hard as I tried, I could not overcome these difficulties in teaching; I finally had to retire early. Now, I live on two acres in the country and tutor on a one-to-one basis. I finally feel that I can cope and offer something to the world. Once a week I go "into town" to buy things not available where I live, but I can stand it for only so long before I simply have to get out of Dodge.
If I had it to do over, I would have chosen a profession that allowed me to have a quiet and stimulus-subdued environment. I'm not sure what that would have been as my forte is with words rather than math. At least retirement is lovely.
