Could I have Asperger's Syndrome?

Sure, it's a very good possibility. You have all the major symptoms and many of the smaller ones too. You would need to be evaluated by a psychologist or psychiatrist who specializes in autism spectrum disorders. I don't know any specific clinics in Maryland, but your doctor or a school counselor should be able to point you in the right direction. Unfortunately, the diagnostic evaluation is a bit pricy. You may be able to find someone who will diagnose you for a low price, but you'll need to do some research. Talk to your doctor, and contact clinics in your area to find out how much they charge for the evaluation. Worst case scenario, you put off getting the evaluation for a few years until you can afford it, and see a counselor (does your campus offer free counseling?) in the meantime.
