Stomach Pain, Abdominal Pain & Diarrhea.

Its all started on April 30, 2017 and I've been suffering pains on that day, I experienced on that day with at least 5 bowel movements. On May 1, 2017, its only 1 bowel movement and I forced myself through lying down so that I can lessen the pain and I intend to sleep since on that day is a feast and there is a lot of visitors, I did that so that I don't feel embarrassed and humiliated to the people. On May 2, 2017, its only 1 bowel movement and same pains and I intake 1 loperamide (diatab - 2mg capsule) but I don't think so it will heal me because I am still feeling pains and I am definitely not feeling well. Today is May 3, 2017 (12:33 AM) on my time zone GMT/UTC + 8h. Please help me, I really want to go to school at 10:00 AM.
