Hello Sam,
I'm the mom of a young man who sounds so much like you. He went of to university a year and a half ago. About half way through his first semester, he quit going to class. Right before finals, he panicked and withdrew from school, all unbeknownst to his dad and me. He had also gone 'incognito,' difficult if not impossible to contact. His dad and I were so concerned, because he's also Bipolar, OCD, and ADHD, and had contemplated suicide.
Our son took a year to work at an entry-level job and attend a few classes elsewhere. Now he's back as a university freshman (again), saying he's ready for the challenges. But I'm not so sure he is, he's not communicating again. My heart goes out to him. I know he so sincerely wants to be a friend and have good friends, and a girlfriend. But this is about the central challenge of Asperger's, which I believe is Empathy.
What you're experiencing is not your fault! Empathy is the bridge that those human connections are made of. It sounds as though you've learned the behaviors that friends do, but it's not really about Acting thus & so, it's about Feelings and Emotions that I'm not sure aspies have access to! Or if y'all do have access, it doesn't seem that way to the people you'd like to connect with. For example, I think my son 'loves' me, but if that's true, why has he shut off contact?
I too am interested to know what you're studying. Many aspies end up in technical fields where aspie-ness is not so much of a liability. But my son's studying English because he wants to be a poet -- I think to be able to express his angst -- so much like yours -- in words. He also wants to teach.
I just want to say, Sam: Courage! So what if you're not like everyone else?! Do work that's meaningful to you that makes a contribution to our world. Your work will be its own reward. And people will eventually seek you out because of your wonderful contributions, as you will seek out like-minded colleagues and kindred spirits. If you have other passions besides your studies or your work, attend organized meetings and outings that relate to those passions. (Me, I'm an outdoors nut, I love to help protect the environment and have hiking outings, etc. ... I let clubs do the organizing work!)
Do your best, be true to yourself, don't panic. Talk to people, and realize that, some portion of the time, that won't 'convert' to friendship (it's the same for all of us, believe me).
My heart breaks for my son, whom I don't even really know any more. And my heart goes out to you too, Sam! All the best!
