The word I would attach to how you feel is "uninspired," a lot of people go through that, might I suggest trying something new, anything at all, something just to get you out of this funk. It's all about breaking the routine, so even though school is supposed to be more important at this point, I read one of the comments earlier and agree, go out on a friday night, find something to do, recover saturday, and do your studying sunday. Other than that things like this can have simple solutions, order a book of something you're not familiar with. My suggestion would be the Dhammapada which is essentially the bible to Buddhism, and what's great about it is you can pick out a random page and just ponder whats on that page meaning you don't have to dedicate a large amount of time to it. Another simple solution is just try a new hobby. Go for a bike ride or something to clear head. What might also work (and this might seem counter-intuitive because obviously this is something you love to do) but just take a hiatus from anything dealing with your computer. I'm assuming you're some sort of programming major and I've seen people take a break from something they love and when they come back to it they attack it with 10 times more passion than they had when they quit.
Hope that could help in anyway, I'll be brainstorming more things through-out the day.
