Welcome to 3FC =)
You're not alone. New people, or people who've been here a while... we all have the same goals. Healthier.
Have you had a chance to look around? There are a number of support groups where you'll feel quite welcome! There are age-based groups, under Diet Central there are sections devoted to different types of plans, there are areas for those looking to lose specific amounts of weight, there's a challenge area if you need a boost.
We don't bite! We want very much to encourage and support every member who needs a hand, and to push those who need a kick in the bum along the way.
Don't be shy about posting wherever and whenever you feel comfortable!
Best of wishes and I hope to see you around the boards!
