Go and see your Senior Tutor, if you haven't already, and make sure s/he is fully aware of the situation. They'll be able to talk you through any options available, whether that's degrading and starting the yaer again in October, or just plodding along and catching up. I guess that depends on how long you're in hospital. I know what you mean about not wanting to leave the course for a few weeks, but it is do-able, even at Cambridge. I came home for a week earlier this term due to a number of reasons, but my Senior Tutor was very understanding and is now doing everything he can to make sure I feel able to stay. And, yes, catching up has been a bit tricky but I'm getting there. Let's face it, the longer you deny yourself treatment, the worse you're going to get, and you won't be able to carry on studying anyway, especially in an environment such as Cambridge. Get yourself to hospital, and I hope you feel better soon. xx
