cuttlefish and jadenei,
kudos to you for continuing your education.
as said above, talk to the ADA resource person - be it an advisor or a special office - at your college. A note taker might be just the thing, and a lot cheaper than a new laptop as the school pays for it. Though that lighter laptop would be awfully nice....
The social thing is hard - I was never a late night person even before lupus. So the college scene was pretty lost on me as well. If there are things you enjoy, consider joining a group on campus that has those interests. I know our campus has dozens of groups ranging from Black Student Association to Fashion to Feminists to political groups. Many of their meetings are during the day, as they work with faculty advisors.
Even if you can't take a full load, keep at the studies. It is so worthwhile in the longer run.
