Congratulations on starting to make healthy steps for yourself. I'm sorry your family is not supportive, but support is what we have a lot of here on FitDay. Look around the forums and jump in, ask for help or answers. We have a very active forum in the Women's Corner called the 7-Day Motivational Thread. We usually start anew on Mondays but you can jump in whenever. Hope to see you over there, or elsewhere around the boards!
And now that you don't have to be perfect, you can be good.
