TMIII stomach issues?

Sunday morning I woke up at 4am having to go to the bathroom, it was like a liquid diarrhea. This kept happening like every 20 minutes. I went to work and felt AWFUL, nauseas, still having to go to the bathroom so often. I got home from work, took a Nap and when iwoke up I had a 102° fever. The fever went away in like an hour and iwoke up this morning feeling so much better. But thennnnn I had to go to the bathroom. Now it’s liquidy dark greenish diarrhea and my abdomen feels SO bloated and hard. WHAT IS HAPPENING.!?
