I live a very stressful life. School, parents yelling at me all the time, dog sick, blah blah blah. When I'm @ my real dads I feel fine... But when I'm home I get Very sick, and start to throw up. Now everytime I get stressed I throw up, its embarassing and I need to get rid of this problem. Please help.. Created by Boy, You're My Lucky Star

Stress can have a big effect on your digestive system, and cause a variety of problems. Talk to your school nurse or guidance counselor, and talk to your real dad. Also, see a doctor. As the person above me said, you may have an ulcer that is being aggravated by stress.
