Welcome aboard!! It does sound like high functioning autism. I'm in the same boat. I don't seem to understand internally the social rules and cues, and thus I don't usually comply to them, unintentionally. Going to a therapist for me would be the last thing next to be dead. Society is merciless and blind for differences. There is one of two ways: either you conform to the norm even if you are not "normal", or be ostracized and ignored. Both are difficult options. I's sorry if that wasn't helpful, but I'm struggling in fitting in as well, and cannot accept both options. I feel I'm forced to be someone I'm not or do something that I don't want to do just to please others and feel I'm "acceptable" to them. You have the right to be angry. Just try to channel it outside you. I forwarded this anger inwardly, and it becomes/strengthens my depression.

Why did you mention ADD? I didn't read anything that implies you might have it. Are you organized? Can you focus when working on something?
