where to begin ...?

I'm 27 and even though i knew i had some sort of issue by the age of ~16 i believed i couldn't afford a psychiatrist and I'm seeing a nurse practitioner now for my issue because my school offers one for a low cost. he's saying that i have "traits of borderline" I've been going to him for about almost quarter of a year now but to be honest I can't for the life of me feel like i can tell him why i actually went to see him in the first place. I've had issues trying to communicating with people and I don't really understand human relationships all that well ... and that's kind of what's causing a lot of issues for me I think maybe I don't talk to people because i find most people to be frustrating when it comes to emotions, when i comes to strictly non emotional things I'm great but the moment you introduce emotions i kind of freak out one way or another. Also I may have made someone really really really uncomfortable online 3 years ago and i seriously don't know how to deal it (it's a girl ... yep ... had a crush on her since i was about 11 ... she's married now grats if i had nothing to do with it but ...).

And then, since you mentioned having had issues with trying to communicate with people as well as understanding human relationships, here's a link to an article on the subject of Asperger's Syndrome:
