I have ADD too. I think ADD make social anxiety much, much worse. It's one of the main reasons why I don't look for a job. People try to tell me how to do stuff and I try to listen to them, but get distracted by my thoughts so god damn easily. I look like an ass when i don't know what i'm doing after being told like 5 times. Sometimes people assume i've got some kind of mental retardation or something which bolsters my anxiety through the roof.
