Recently went through a breakup..its been two weeksthe first week i didnt eat anything but did drink water then i slowly started eating but very littletoday i woke up with diarrheais that normal ?

Diarrhea is not normal, neither is fasting for two weeks. Eat some soft foods like bananas and gradually increase you intake of your usual foods. Drink fruit juice and/or electrolyte drinks. If diarrhea persists take Imodium and if that does not resolve the matter in a day or two, see a doctor.

Your diet and mental state has caused this situation. Change diet and find a hobby or sport to ease your mind and body. Seek a friend, male or female to talk to or a new partner. You are young enough to find a new happiness, stay strong and healthy.
