ARGHH I'm SO DEPRESSED!?

I have worked so hard to lose weight. I went from 180+ lbs at 5'3", to 127 lbs. I gave myself a make-over, grew some self respect and have tried to maintain a positive confidence. But no matter what, I can't find somebody to love. Has my experience made me so cynical to men that I just always come off as a total b**tch?? Why does no one look at me? I feel more invisible and lonesome than ever, far from home, and desperate for someone to love me unconditionally. Is it too much to ask?
