Do I have Asperger's?

I am currently 22 in college and I come from a conventional Asian family where my parents are not familiar and do not believe in mental disorders. As a result I have never been diagnosed and all throughout my life I was labeled shy. I have made no more than 10 friends the past 9 years and I always felt it to be difficult to maintain a well relationship with people in the long term. I always thought of it to be very hard to read other people's body languages and realize things they might be implying. I often find it frustrating when I discover that I made people feel bad and reject me without understanding the reason. I also tend to repeat the same routine, such as going to the same place for lunch and buying the same thing every other day. Often I realize that I have alternatives after repeating a routine for a while. I have always liked to sketch pictures of cars whenever since I was little and I get fascinated at things that are explicit and easy to understand such as video games, cars, geographical facts, etc. I have been wondering for the past few years about this after reading about Asperger's and finding the symptoms familiar. I have been feeling depression, frustration, anxiety, and loneliness for as long as I can remember but nothing that I've tried improved my situation. I won't feel bad learning that I might have it for the first time if it explains all of the above. Thanks in advance for your input.
