I need Help

So I broke down and joined Weight Watchers.  I have nothing against these weight lose groups, I just never thought I'd join one.  I was so determined to do this all by myself.  But the truth is, I need help.  I'm bigger then I've ever been in my life.  I'm angry, frustrated and disappointed with myself.  I almost feel like giving up.  But I know I can't and I know I can't do this alone.
