Let's try this again!

So, I first lost weight, almost to my goal weight, two years ago with MFP. Now I have gained it all back and then some. I am in two weddings this summer and would like to feel more confident. I also have been getting hints that I will be the spotlight in my own wedding, and I want to be prepared in case it happens! Anyone willing to give and take support and advice, feel free to add me :)
