Ugh, I hate catching myself in the mirror too. It almost always disappoints my expectations.
I, too, fear that I'll reach an impossible-to-break platue before I make it to my goal. I've never been under the weight I am now, so my goal weight might not be physically possible for me.
What also bugs me is how long it takes
Maybe it doesn't bother me ever day, but some days you wake up wondering if you'll ever get there. I can't speak for anyone else on the board, but my progress hasn't been linear, and it's been pretty slow, but I am progressing...
