friendly competition?!?!?!

Looking for any groups out there where people are looking to have a friendly weight loss competion or something? Needing some motivation and to be able to hold myself accountable. I don't have people around me who are supportive of my weight loss and I'm looking for some help/advice whatever to help keep my head in the game. I have been a member for over a year but have put weight back on in the last 6 months and just feel lost and disappointed with myself. Anyone wanna help PUH............LEEEEZ???
