Suspicions about having autism.

Recently, i got myself thinking about the Autism spectrum, this subject always interested me, and researching about along with experiences i had, i'm starting to suspect about have It, and it's scaring me alot- 

The most part of people i know (friends, colleagues) already asked me i have some mental problem, and last week, it happened two times in a row, and one of the people he said as if he was sure I had autism. I don't know how i can react to all this situation, i'm just scared and stunned and i'm afraid to ask to schedule an appointment with my mother cuz i never talked about this to her in a mature way.

I started to notice and study my behaviour in everyday life and... Damn, i can really have something related with this, like my hypersensibility to sounds, smells and bright lights, avoid to do eye contact, Difficulty socializing and maintaining/initiating conversations, difficilty understand a joke or speak, it's all soooooooooo scary to me ;^;

And well, i guess i'm gonna ask my mother to do an exam, i do really want to know the truth cuz this bothers me since a long time ago and i can finally have the chance to understand myself for once.

Thats it, If you think you can help me or know a specialist, i would appreciate the help, byyyyyyyyyyyyyy ;>
