Looking for support and a place to hold myself accountable

I am 32 years old and weigh 310 after having my 2 kids. I am a person who has dieted all of my life and in college finally got down to 190 and was so happy with myself. I started to put on the weight and then once I got pregnant with my first child I put 100 pounds and then 60 with my second child. Every morning I start out and think today is going to be my day, and then something comes up and I blow it. I started this page after a coworker suggested it and and i am hoping to add some friends that I know will help support me and hold me accountable to making sure I logged in everything.
