Ok, my fellow sensory-overload peeps, tell me how you survive the world.
I'm gonna give Loops earbuds a shot (feel free to recommend others. I haven't yet had a chance to see how well Loops work for me).
The main other thing I'm going to try is to very specifically identify the things in a given environment/situation that are causing discomfort. I know in general what kind of things cause me problems, but maybe I need to get into the details & see what's happening.
