I know exactly what you mean! I look back at photos when I was about 10-15lbs away from my goal weight, and can't remember why I loathed my looks so much. I hated myself back then. I guess in a way, I'm glad I gained more weight, because I know I'll be more appreciative when I get there again.
Good luck, to the OP. I know it's a drag to be "almost there", but it's going to happen! Keep your chin up! :-)
