Welcome Thisibelieve, you will get plenty of support here. I agree perhaps a visit to the doctor is in order
Be kind to yourself, the housework can wait a day or two, drink plenty of fluids. If you can't bring yourself to eat get some diet shakes, just to get the right nutrients in to you.
Keep close by for support, we have a Class of September 2013 thread for those quitting this month, or the Year and Under thread is fab too.
