Is there something wrong with my gall bladder?

So starting today i have been having trouble. I took a energy pill with an energy drink today before working out(i know it sounds stupid). Well i tanned after working out and thats when i started having horrible nasuea(not sure how to spell it) and i was shaking. As the hours progressed it got worse and we were on our way to go eat. When i am riding in the car or even walking my head hurts a lot, i hardly ate anything, and my stomach was hurting every time i ate a piece of food. I have had pain under the right side of my rib cage but now its just the pain and a little nasuea, also my spit is white and foamy. Can anyone tell me whats wrong? I am only 14 years old. Plz help
