I found another great article on controlling overstimulation.
This is exactly what happens to me...the description could not fit me any better. My problem, though, is my threshold changes so much. One day I can handle a visit to the grocery store...and the next day, I can't even handle a walk around my complex. Another day...I'll have a 30 minute conversation on the phone, and another, not even 5 minutes.
I'm hoping this program that I'm in will increase my threshold...and/or teach me some good tricks to control it.
Check it out...some good information here:
