Sarah - I truly never thought I could... or would... At 22 stone, my sole preoccupation was being "covered" and "decent".
Ironically, I always find that losing weight encourages me to want to lose even more... (whereas the reverse ought to be the case... the more I gain, the more I eat, and then I hide in "tent dresses" and skirts...).
"Feeling slim" is the key... not necessarily "being slim". Right now, at 71.5K, I FEEL slim... because I've just lost 8.5K and I'm "in control" and on the way down again...
However, when I went UP to 70K previously, I FELT horrible in myself, hid under baggy clothes, and slouched.
I remember at 100K going to a public swimming pool and strutting my stuff! (Anyone surprised at the amount of water displaced at MY entrance on the pool could stuff it - I felt good! I'd lost 41K!)
