Tired, over-eating, and feeling antisocial all the time! What the heck is wrong with me?

I've had a compulsion to binge since I was a kid (actually, I was bulimic in highschool)..but back then I wasn't exaughsted all the time and love socializing and seeing people. I had a baby a year ago, and ever since then I've been unable to lose weight..I don't feel like doing anything but staying home and sitting on the couch..my overeating has gotten worse, and I hate talking to people now, and even my husband irritates me so much now..what the heck is wrong with me?
