Unfortunately it's not uncommon in Asperger's. I used to wonder why other aspies worried so much, sigh. I feel like I'm being punished for not getting it.... Now I do.

It's flipping hard to turn the worry off. It's a worry about different things but the worry is exaggerated. I'm scared someone will ring the doorbell, I'm afraid of my landlord, I'm afraid people will be mad at me, I'm afraid opening my mail... I can't even explain what I expect. More and more I can only relax when I know I have a long stretch without anything I need to do or have fixed or whatnot. People expect me to come visit and when I pack I feel so stressed out. I can't relax until things are done with. I lose more and more life just waiting.

They say you should have a special worry time where you are allowed to dwell and when it is up you are no longer allowed to think about the worries. I know I tried it before but maybe I didn't try hard enough?
