How Can severe Abdominal Cramps Along With Diarrhoea Be Treated?

Hi! For the past 4-5 days, I have been having non stop stomach cramps. Tuesday night, It started out after hearing my Mom be depressed due to her and my Dad divorcing. I got really depressed and my stomach began to cramp. Then I developed diarrhea. 1 Morning later, I felt even worse, as I had missed school that morning, but then after sleeping, I felt just fine for the rest of the day. Another day later, I developed diarrhea again but without the cramps. That wasn t until much later, like after I donated blood. For part of yesterday, the diarrhea was really bad, It hurt and bleed to even wipe, at least until noonish. Now hardly nothing comes out. Now I still feel like I m going to puke but all that comes out is water. I can t eat, or use the bathroom. I ve been eating whatever I could stomach, and drinking plenty of water. I don t know whats wrong. Do you think it could be emotional stress?
