The emotional aspects of weight loss

I'm 26 and about a month out from surgery.  I feel numb emotionally too.  I know I should be excited and pumped that I was given this awesome gift to get my life back but instead I just feel blah.  I also worry about putting myself in the dating scene.  I'm still not happy with myself and don't really want to have to explain to someone that I had surgery.  I just don't think I am emotionally ready.  I do get nervous though that I won't ever meet "the one" but I guess that's why God gave us dogs right?!
