Suggest Treatment For Diarrhea And Stomach Pain

I have been feeling sick since afternoon after lunch. I have been having stomach pain, sometimes there is a sharp pain. I have been to the toilet multiple time and each time, I have diarrhea. Some times I have to rush to the toilet as it is leaking out.
Right now, 5am, I wouldn't say I'm better but I do not need to keep going to the toilet after taking some charcoal pills. However, I can't sleep as I keep 'hallucinating' that my body pillow are bodies and I'm in a TVs scene. My head hurts and my mind feels in a mess. I suspect I'm having a fever but do not have a thermometer to check.
I feel thirsty yet my stomach feels bloated and stuffed.
My question is: should I go to a hospital?
