Hi Dorfin! Welcome to Wrong Planet. Check out the forums here. There are some specifically dealing with Autism/Asperger's stuff. You can do some research there to help you. At least one of them will point you to some online tests you can take. After taking the tests print out copies, so you can show them to the doctor if and when you go. Also make a list of symptoms you have that seem to match those on the Autism/Asperger's spectrum, and you can bring that along to the doctor, too.
Based on things you described about yourself, it is possible you might be on the spectrum, but you need to do some research for more info.
I am also not fond of going to doctors. I am self diagnosed, with the help of personal research, an online test, and my own sister's independent opinion, before she even knew that I knew about Asperger's. If it walks like a duck, looks like a duck, and quacks like a duck, it's a duck. Well, I'm an Aspie, and it was a big relief once I finally knew what was wrong with me.
Just remember, you are among friends here at WP.
