Kelsey i'm afraid you are damaging your body a lot. Throwing up like that destroys your esofagus and your digestive system, it can give you loads of diseases and you can end up dying... Throwing up what you eat isn't the best way to feel good, on the contrary! You feel better for a while and then it goes away and you feel bad again.. Most people who do it are afraid of losing control of something in their lives, so they start controling their own bodies and end up hurting themselves really seriously...
The best advice I can give you is to talk to someone you trust and you think will be understandive, because you really need to stop doing that. You deserve a happy and healthy life and that's just not the right way to go!
Not sure I helped, but I really hope you get through this the best way possible!
Take care
