Need A Friend For Motivation!

I would really like someone who is constantly checking up on me to see if I'm doing what I need to do. Someone who will support me, etc. I always start working out and losing weight and then I stop and go back to old habits and I've done a lot of changing for the better this year, and I'd like to add losing weight to that list. Looking for a penpal, Facebook pal, whatever. Just someone who wouldn't mind keeping me motivated!
