1)Get out and make some friends, they will keep you busy and you won't notice that you're not eating.
2)Try to exercise for about 10 minutes everyday, working your way up to 45 minutes.
3)Cut your portions in half.
4)Start drinking a lot of water, and ween yourself off of pop and high calorie drinks. If you can't keep track of how much water you drink, fill up a gallon milk jug with water every morning and make sure you drink all of it by the end of the day.

I hope I could help. I believe in you, you can do it and make your life better, good luck!
