I have uncontrollable yellow diarrhea and vomit, and had a lot of abdominal pain. is this serious?

Yes, this is not normal. Please get seen in person today.

That combination of vomiting,diarrhea and abdominal discomfort can occur with a viral intestinal tract.infection or food poisoning. Loss of fluids leads to dehydration, electrolyte imbalance and renal failure. For this reason I recommend that you proceed to the hospital emergency room where prompt evaluation, testing and care are available.

Go to an urgent care center immediately, or hospital ER. Don't try to treat yourself.
