I'm surprised how many people were able to spend lunch in the library. I was stuck in the cafeteria. Everyone would be talking and laughing and I would be having an anxiety attack because I didn't know where to sit or what to say to anyone.
I used to go to the school nurse a lot saying my stomach was hurting and I needed to go home. It worked but just reinforced my avoidance.
One time I went to this employment seminar, and when I arrived I saw this group of people standing outside waiting for it to start. I didn't want to have to walk past them, so I drove around the town again to try to pass some time. When I got back to the building, I walked in only to find that they started a couple of minutes early. The door just happened to be in the front of the room too, so when I opened it everyone was staring at me.
If I want to use the mirror in a public restroom, and someone else comes in, I hide in a stall and wait for them to leave. I will then try to use the mirror again. If somebody else comes in, I sometimes will go back in a stall until they leave.
When I am at a stoplight and a car pulls up next to me I will mess with the radio, so I don't have to figure out what to do with myself.
At my one job, I would eat lunch in my car and pretend I was reading. I was really trying to read, but was too nervous to actually comprehend anything. People would walk by the car and wave, while going out to eat together.
