I'm the kind of girl that just loves to eat. But I want to lose wait for my wedding. I don't have a card to order anything and I can't seem to get the motivation to get up and work out. I'm starting to think I have the binge eating disorder because all I think about is food and I even eat when I'm no where near hungry. I need help I'm not huge but I'm no healthy either my fiance loved think girls but he doesn't mind if I lose 10-20 pounds!!
