I know the feeling *exactly*. Just dye your hair brown and we would have been twins. Although I would have been the shorter, uglier twin so it's probably for the best.
But as far as a goal weight, I'm almost to 120 and I'd say it's a totally doable goal (not overnight, but doable). I'm a size 5 or 7 now in most stores (or even a 3 were they heavily vanity size). Although you do seem to be more hourglass-y than my linebacker shouldered self.
So that might make a difference.
Good luck! And you can do it!
