Been there, felt that... They should have a t-shirt for that feeling, eh? Truthfully though, I'm betting you put a great deal of effort into your assignments and strove to do your best. Therefore, whatever the results, you can for the moment congratulate yourself for seeing the semester out to the end. I think everyone else is going to give you similar advice to what I'm about to say... but I'll put it in a context that should be a bit encouraging. You should go out and do something fun. But here's the thing about my advice that's different... It needs to be something completely new -something you've never tried before - or something you never have time to do except on breaks. New is better. And the more activity and concentration the task requires, the better. Movies work really well too though. Another option is to follow through on whatever promises you made yourself mid semester whilst trying to find the energy to keep going... I know I promised myself I'd go out to the beach (yup, even though it's winter) while trying to get through an absolutely excruciating research paper, and now I fully intend to go forward with that plan.
