**I am sorry to hear about your situation and May Allah give your Professor good health. **
I really think that you should (if you have not already) start talking with other Professors/Researchers to see if you might have an opportunity to work elsewhere. Use these few months to network with others in your field, seek out opportunities (go back to school for Masters, Doctorate) or even apply for jobs that you might be interested in.
Easier said than done, right? Which is why you should treat this time as a valuable resource where you can explore possibilities and make the necessary connections. Assume the worst (that you will not be able to return in Feb 2011) and plan accordingly.
I wish you the best and do feel free to share your thoughts and what you are up to.
