Second time around

I am back after a two year hiatus (not sure if that's how it's spelt or not). Lost ten pounds back then have pretty much avoided a scale since then and got on yesterday and about had a heart attack. I'm at my biggest weight ever even while pregnant twice. Anyway, I'm miserable. I need to act now. I need accountability and motivation. I want to do it, but then everyone else is eating something and there goes my willpower. Anyway was going to sign up for ww but decided to save money for myself for rewards like at my 10 pounds lost mark maybe some uggs or a new northface jacket. I'm trying to get motivated and stay focused. Anyone want to help with my motivation if so add me or let me know and I'll add you thanks for listening. Good luck to you all
