change needed

I want a change. I don't know where to start. I am near 300 lb so I guess I need to lose some weight. Maybe it will help my pain. I don't think it will make it worse. I need some support. I know almost no one reads this but it is good to put it out there. I need a plan. Well besides applying for the Biggest Loser. I would like some help . I could put this out on facebook but I am chicken.
