Sometimes it just takes your mind a while to catch up to the changes your body is going through. I felt fat all the time until I got down to 150. It took me a whole lot of time before I felt really good about myself as far as my weight is concerned.
Even now I still have those days. Usually it's when I see how much more weight I have to lose and then I start thinking about it too long and feel awful!
I know it's weird...but perfectly normal.
