How do I get an Asperger's diagnosis without health insurance?

I am pretty sure I have Asperger’s syndrome. When I was in the second grade I was pulled out of regular classes and put into special ed. I stayed in special ed till I graduated high school, but always felt like I didn’t’t belong there. Now I am 27 and cannot hold down a regular job working with the general public. I get anxious doing a lot of tasks unless they let me do something quietly by myself or in a small group of people that I can relate to. Most of the time I get placed into situations that I simply cannot handle and (shutdown). I don’t feel anxious all the time, only during certain situations, like running a cash register or drive thru window. Crowds and loud noises make me shut down. I simply cannot hear myself think and will start to speak in monotone. So I did a lot of research and sounds like I am an aspie. I do not have health insurance but would like to go to a doctor for a diagnosis. Hopefully it will be a quick diagnosis and they won’t say I need to go to therapy or on medication. I really do not like taking pills. I would rather just have the doctor recommend a job for me that I would excel at. So my real question is how do I get into a doctors office without insurance? Do I need to apply for Medicaid? The healthcare.gov site still does not work right…
