Take a hint and go away?
Insult them back and cause an argument?
Say nothing and get depressed?
Laugh at them? (I don't know if I can do this.)

I am a dour person. I have a lot of issues (emotionally and physically) and have always had a hard tiime making and keeping friends and jobs.

I seem to have ADHD and, in order to keep track of things, focus very hard. I misinterprete people easily and have difficulty with conversation.

It seems that no one wants me around. I isolate almost all the time.
