As someone who struggled (and is still struggling) with bulima. I understand your pain. Throwing up after you eat is bulima, and it will not help with your body image. If it helps I can share what my experiences were: I was 14/15 and I was doing it unconciously for monthes. Not after every meal but pretty regularly. I managed to convince myself that I just felt sick or that my stomach hurt and that's why I was doing it. It wasn't until one night when I was writting in my journal and I got up to throw up my dinner. After throwing up I took a look in the mirror and it hit me that I looked really sick. I was pale, with terrible dark circles and I was really really thin. It's like I suddenly woke up and realized that I was making myself sick. I went back to my open journal and found the last words I had written were "I feel fat and disgusting". It's a struggle but you have to stop, it won't help you feel better about yourself :)
