I Have Had Diarrhea For A 2 Weeks. I Am

I have had diarrhea for a 2 weeks. I am bloated. I have not lost any weight. I am vegan and only a few days ago I added supplements for CoQ10, Calcium, Weight loss herbs, and a multivitamin to my daily medication. The medication my doctor requires is plavix, Super B complex, D3, Depakote, Effexor and Remeron. I really am trying to lose weight but now my digestive system is so week that I can not hold any food at all and have to rush to the bathroom 10 to 15 mins after I eat. What is going on?
