Out of the Game

I need help getting back in the game. I was losing steadily, but now I've given up hope. Well, not really, I still do want to lose weight and I know that I can, but I have no support. My grandma always just pokes fun of my weight and hubby lets me eat pizza, so I don't know who else to turn to. The girls at work are kinda helpful, but the other day we all bought pretzels! HELP!
