Since I had no idea I had Aspergers, nor depression, nor anxiety, when I went to college - all of that was stacked up against me. I totally thought I was going to arrive a college and finally be around likeminded people and have friends and live out my glory days - WACK! The reality hit me in the face. I had no ability to meet and make new friends, and most of the people there were not like me at all. I got severely anxious and depressed, not knowing why this was so. Now I know that, in addition to social issues that I have worked on since, the environment itself was way, way too much for me - it caused so much stress! I needed lots of alone time....and when living in college, there was no alone time - perhaps in the bathroom stall, but even then, people can come into the bathroom, and you can't stay there forever. Looking back, if I could have just been in a quieter environment that I could control, with more privacy, that would have been a HUGE help. Also, I wish I hadn't compared myself to other people - I felt like a complete freak and failure because everyone else was out partying on Friday and Saturday nights - and bragging about getting drunk, etc. But in reality....that's just not my personality - but I didn't know well enough and wasn't confident enough to stop letting that hurt my self-esteem. It was extremely lonely not having friends, but I think these factors I mention made it a lot worse, which made it even harder to improve socially....
I just wanted to pass along this advice, if it helps at all. 1) Try to know yourself and how Aspergers affects you - and accept it, don't compare yourself with others because of it and feel bad. 2) Try to gain control over your environment as much as you can so that it won't stress you out. For example, there was an option for a single sex, "quiet" dorm where I went to college - but I was pressuring myself to learn to be more comfortable with guys and more outgoing in general, so I didn't choose that option - whereas really, that dorm would have been perfect for me. A private apartment would have been even better, but that wasn't going to happen. Whether on or off campus, try to be mindful of your environment. 3) Try to read p on social skills. This is a great website which I found really helpful, he has also written a book (which I would like to read since it's hard for me to get through all of those articles), but here's the website:
The Social Skills Guidebook | www.succeedsocially.com . Also, if you have social anxiety, "Diagonally Parked in a Parallel Universe" did help me get started with basic social interactions.
4) Hopefully in college, when with others who are studying biology, you can share that interest as a starting point for friendship. It is a different type of population at college than in high school, so that could help!
Best of luck
