I REALLY NEEDS SOMEONE'S OPINION, PLEASE!?

She should go to the emergency room. ASAP. I'm no doctor but the only stomach pain I've heard that hurts so bad is caused by kidney stones. Which are aculated rocks of salt that stick to your kidney. A doctor can vacuum them out or she can drink ridiculous amounts of water and cranberry juice and pee them out which will be painful as well. But again I don't know what she has so I wouldn't suggest giving her drugs. She should go to the hospital.
