Feeling Hopeless and Unsexy

I am feeling pretty crappy and dont really have anyone else to go to. I've talked with my SO about it and he is so sweet, but he just doesn't get it. I feel like an alien in my own skin. My boobs leak. I have horrible stretch marks. I gained so much weight. Everyone said I would burn extra calories with breastfeeding and that the weight would start to come off, but it is just not at all. I was working out before I went back to work, but now I just dont have the time or energy and I dont want to be away from my sweet baby anymore than I have to. Any moms out there feeling this way? Any suggestions? Here is also a pic of my precious girl to hopefully lift the mood.
