Taonuviel, do whatever you need to do to get yourself healthy - even if it puts you behind in school. It took me 6 1/2 years to complete my undergraduate degree and I don't regret it at all. I gave myself breaks whenever I needed them. At first, I thought doing so was irresponsible, but now I see that it's the most responsible thing I've ever done for myself. If I was feeling overwhelmed by my emotions, I'd take a semester off and it would always do me a world of good. I'd be so much happier and my grades would be so much better when I went back.

And maybe you don't even need to withdraw completely. I know it may be hard, but try to talk with your professors and see how they might be willing to work with you. Most hospital stays are short term and missing a few classes might not be as big a deal as you think.

Also, if your school has a disablities office, go talk to them. In fact, I might talk to them first because oftentimes, THEY will do the talking to your profs, and will sort of force the compassion on those few that don't come by it naturally.
