Confused and angry.

I have to get this off my chest.
For awhile I have been pondering over all of my insecurities and perhaps have been a little obsessed with all the problems of my childhood. In other words, I've been wallowing in self pity.
I've been doing excessive research on psychological disorders (In attempt to prove to myself that I'm not mentally ill) and fell upon information on Asperger's syndrome. I found this information via a social anxiety forum while researching selective mutism. Just out of curiosity (and a little nagging feeling) I began reading threads and researching various websites. Why? Because upon discovering that I actually fit in to and completely relate to a group of people for the first time in my life I still don't want to believe that there is a possibility that I have this disorder. I'm looking for reasons why I don't have this and can't find a whole lot. I even took some on-line tests and it scared the living sh*t out of me.
But all of a sudden everything makes sense. It explains everything I've gone through my entire f*cking life! All these memories are flooding back and all these pieces are fitting together. I don't know if this is real or not. I can't even bring myself to say anything to my husband or anybody so I write it in here so my head doesn't explode.
What now?
Do I just wait it out and get on with my life hoping that I'm being overly effected by some hype on the internet and that I will come to my senses soon but I'm not so sure.
Do I try to see someone for a diagnoses of Aspergers or a conformation that I'm crazy & nuerotic? Can I afford that?
I need to talk to my mom but I'm pretty convinced that she has her head in the sand. I know she's had me tested for all sorts of things before. I've had electrodes on my head and hearing tests and spent days looking at pictures and taking strange tests. My mother never told me what the results were. Perhaps she knows something I don't.
My head is spinning and I can't concentrate on my work. (I have two tests tomorrow)
