lose 80 pounds and keep it off

I have had issues with my weight since before I can remember. I was made fun of growing up because I was the tallest kid, not fat but tall. And instead of calling me tall people called my big. I took it the wrong way. I started throwing up my food in high school. I would work out for a week, then stop, work out for a week then stop. In college I was a full blown anorexic. I played college volley ball, I ran about 7 miles a day, did 600+ crunches a day and did this for about 6 months. my step mom even encouraged me. she would tell me how pretty I looked with each round of 5-10 pounds I lost until I was too thin. I saw a doctor, got better, then fell back on bulemia. Then I was in a car accident, my college relationship was over and I was so depressed because I couldn’t run anymore and I didn’t have Noah in my life. So I ate. I moved out. and I ate. I now weigh 245, and I weighed 132 4 years ago. I am 5”10. I will get back into shape the healthy way!!!!
