Am I developing an eating disorder?

Well I've always felt uncomfortable about my weight. I have never been overweight or anything though.
But since I moved to America in summer I've gained 20 pounds. I haven't really thought about food and dieting that much before but compared to before I am almost obsessed with food. My last thought before I go to bed is what to eat tomorrow and to lose weight and when I wake up in the morning the first thing I think about is my food plan for today. I would try to eat as healthy as possible and not eat any junk food. I would count every calorie I eat and feel bad when I ate too much. Lately I started forcing myself to throw up when I have been eating too much, at first I thought I would only do it once, but I did it again and again every now and then and now I do it every day. I would find myself not sticking to my food plan and eating something that's bad for me and then feel really bad about it. Sometimes something overcomes me and I start eating everything I find and way too much, even if I am not hungry anymore I would continue eating. I would be disgusted by myself once more. I would eat that food secretly because I would be embarassed.
Then I would go and puke once again and think about starving myself as a punishment for some days but I probably wouldn't resist. Is there something wrong with me?

there is nothing wrong with u as a person,but like me your environment maybe contributing to the way u feel and think about your body which may have led you to where u are today.i struggled with the same thing since i cleared high school.i have always been tall and this made me stand out almost everywhere.when i cleared high school i was abit big though not overweight according to my BMI but all everyone was seeing was how big i was.this led me on a road where would do anything to be thinner and remain that way.i have been like this for almost 6 years now being obsessed with what i eat.what made it even harder for me to like my body the way it is.is the fact that people started commenting on how much they liked my slim figure especially with this constant pressure for women to be small.even now at 23 years as i try to deal with this each day i realise that the greatest contributor was the things people kept saying about my body and the media and how vulnerable i was at that time not to be able to remain in control of my own mind and body.just know you are not alone and my advice to you is to especially focus on what wrong messages you are getting from people or the media especially about your body.as long as you are eating healthy you dont need to burden yourself so much about your weight.it doesn't come easy for most of us to stand the pressure all around us especially when no one is there to affirm you for who you are regardless of size,shape or looks but it is possible.if you have someone to talk to and someone u can trust with this it is much easier
