I know how you feel. I have felt like my body doesn't belong to me. I cannot believe I still weigh so much. I do not FEEL like an obese person. I never have, and I think that is part of the problem. I don't see myself as an obese person, I view myself as a young healthy person. It is like I did not notice how out of shape I am, or how big I actually am. It is just shocking when you finally realize it. It is like I have been living in a bubble my whole life, and I finally see what everyone else sees.
I did not understand how I got to this point, but looking back I know exactly how I put on the weight - lots of food and little exercise. I am now OWNING my past behavior, and realizing that I can make a change.
I remember thinking that other girls were bigger then me, but now I think I was much bigger then them.

I remember rationalizing the food by telling myself, well I am not 300lbs so I must be okay.
