I was thinking about this the other day and I'll try to explain my thinking below... however, it may make little sense!!!
For me, before I started to lose weight I was in denial. At size 22, all the shops were "cutting their clothes smaller."
I never looked in the mirror properly, and when I did, I saw myself how I used to be, as a size 16-18, not as a size 22.
When I saw pictures of myself at Christmas, I realised I had to do something about it and in January started SW.
Now I am losing weight, I want to see the difference... I look in the mirror all the time, and I see myself as I am, or maybe even bigger than I am.
This has meant that my image of myself now is worse than it was before I began SW, but it is a realistic image, and not an image of a girl who is 3 sizes smaller than you really are.
Anyway... enough ranting from me!!!
Keep your chin up, look at some old pictures, and I bet you will see a difference. If not, go and see someone you haven't seen for a while... I bumped in to someone in the street today and he almost didn't recognise me, and told me I looked amazing... I was beaming from ear to ear!!!
