what to do!

Today is Sunday and I planned to get my homework done. Things popped up and oops... haven't started either projects!! They are big too.. I am also feeling very nauseous and have an awful headache. I'm not to sure what to do? Do my homework and try to bare it for atleast 5 hours or take a power nap which I will probably end up sleeping till tomorrow morning. Both are due tomorrow and my teachers don't except excuses.
