I imagine you are a youngster? Because this seems more "normal" for teens or early 20's, to feel this way, which is understandable.
Older ones, like myself, feel different though and embrace being an aspie, because when you have spent your life feeling different and not understanding it at all, to finally find out why, that is pretty empowering, but had I been younger ie the ages I stated above, no doubt, I would feel the stigma.
I think you need to find out why you feel angry? Is it that you are concentrating on only the negatives? Is it that because you have been diagnosed, you feel trapped ie unable to get away from being aspergic and thus, feel rage at the condition?
Aspergers is different from autism, because even in male's, there is a certain amount of adaptation that we can achieve. We can learn to do things, rather than being stuck with them. Like for example: I can now look people in the eyes, but yes it is difficult still and sometimes, do have to look away, to breath, actually. I can even think: ah I am being too literal here and lower my voice when I am told I am too loud.
If you haven't do so far, why not connect with other younger aspies?
