PLEASE READ! How do you know if you are bulimic?

I've been on this diet for 3 weeks and I've limited myself to a small amount of food options, but I cracked from the pressure of my family eating unhealthy and ate 2 bags of chips today. I felt horrible so I made myself throw up. I made myself throw up yesterday also cause I felt like I ate too much. My body is shaking now, but I feel less guilty. Am I developing an eating disorder?
