I was recently diagnosed with Aspergers syndrome based on these problems that I experience almost daily;
I get annoyed very fast and it can lead to angry outbursts, even violent outbursts, though not towards other people, I usually have a tendency to break things when I'm very angry, and unfortunately it doesn't take much. This happens most commonly when I'm with my mother, and as a matter of fact rarely happens around friends.
I'm not socially awkward towards everybody I talk to, only people I don't know (like I can't ask for directions, help, not even the time, and this would make me late coming home when I had a curfew which would lead to arguments with my mom and she didn't understand how I didn't just ask someone, as this was before a psychiatrist made it clear, and I just explained it as being shy, but she was still pissed and this would lead to high anger, as I said, very quickly) or have formal relations with. With these people I am almost completely unable to make eye contact, and people I try to talk to on the street don't really care and people I talk to formally know I have the syndrome allow my eyes to wander around the room, because I do take an active part in the conversation and listen intently, but I also multi-task mentally sometimes and survey the room and surroundings while I talk. This would sometimes make formal relationships seem like I was acting like I knew more than the person I was talking to and I had a lofty, arrogant attitude, which would lead to anger from me. I also tend to stammer and be unable to explain things I have very clear in my mind in words. Most symptoms generally are a 'struggle' for me because these interactions with other people in which I can't effectively communicate lead to some kind of annoyance which brings me back to the anger. I just always get angry at things in some way or another and this leads generally to me being an unfavorable personality to some people. I've been lucky, however, I have friends that understand me and I rarely even show my symptoms when I'm around some of my closer friends.
