Back on MFP and need motivation/support!

I was on MFP before, but I didn't fully commit. Now I'm back and I think I have a new attitude...I signed up for DietBet, where you bet money into a pot with other players. You bet you can lose 4% of your weight by 28 days. Whoever gets there splits the pot. You can play continuously until you reach your goal! There are a few rules here and there, and ways to verify you're telling the truth about your weight (airport security attire in photo - no shoes, no coat, no jewelry, belts, etc) and you have to write a word under the scale, and weigh yourself at the same time each day.

I buoyed back up to my starting weight of 240 pounds, and that number is highly depressing. I'm looking to get down to 160, then reassess when I get there. Please provide me encouragement, and I'll do the same for you!!!
