Believe me, although 7 weeks is not good it's nothing compared to me. I've had watery diahrea for at least 7 or 8 months, almost every day. I've also had nausea, a generally ill feeling all over, headaches, and a problem with a very fast heart rate. I was recently seen at The Mayo Clinic and diagnosed with Orthostatic Intolerance for the heart rate issue, and Celiac Disease causing the diahrea. You may want to be tested for Celiac, it can cause those symptoms you are describing. It starts with a simple blood test, then if that comes back abnormal, a small intestine biopsy. Good luck with your doc appointments!
