My sister's been having a lot of stress. Well here lately everything she eats goes straight through her. She is on vacation, it stopped. But the other day she suddenly felt like vomiting, she ran to the bathroom, had to lay in the floor, she was about to pass out. She felt better after 5 minutes or so. She stood up and to her surprise, her face was as white as a mountain top after a hard snow!! She's been having chest pains, her heart flutters, with pain in her chest!! Help!
