I can't get up!!!

ok I was doing GREAT on Atkins til Halloween and I have blown it BIG TIME!! CANDY CANDY CANDY FOR 3 DAYS!!! I can't seem to stop myself. I start over every morning and I blow it by afternoon. I am such a sugar addict, MAJOR chocoholic...so bad we've had dogs named Oreo, Fudge, Brownie and Hershey lol. I think my initials being PMS has something to do with it lol

anyway, I feel so guilty and I feel like I'm battling this alone. my kids think I'm beautiful and perfect the way I am, my fiance doesn't want me to deny myself anything. I need someone to kick my rear in gear. I was strong before, I know I can be again.
help please!
