what keeps you going?

Hello everyone, I have been on and off CD for a year and a half and I am currently 4.5 stone down from my start weight. I was just wondering what it is that keeps you going in your dark days? When it would be eaier to cave than not?

I am 25 and have just been accepted to drama school and I don't want to be the big one on the course, so looking for inspiration to lose the last 3 stone xx

1)I plan on going back to school soon so that's my incentive too.
2)The extra weight is making me dysfunctional and ruining my sociallife.
3)I want to be able to shop for clothes which I like, not just the ones that fit!
4) be able to wear jeans and still cross my legs

i lost over 3 stone and got down to 9st 3lbs in 07-08 and i looked great and felt great, i am now at my biggest and i ust keep thinking how good i felt before and i have pictures cellotaped all round the house of how i was back then x
