I suspect that i have asperger's syndrome or social anxiety. i'd like to get it checked out, but my mother would never let me. i've got many questions. how do i deal with that? due to extreme interest i can't stop myself from doing research on both.

Some basics: Obsession over any label is not healthy. You are listed as 18 which in many states makes you capable of making your own healthcare decisions. In my state I would be required to get permission from a patient your age to discuss any health related issues with your mother. Try to schedule a visit with your regular doc or a local clinic where you can go alone. They can help you develop a plan.
