You seem to need to be involved in support groups. Maybe you could look into codependents anonymous, or a 12-step group for survivors of dysfunctional families. There is also this online family right here. Service and volunteering are another good option. What goals do you have for your life? Anything you always wanted to do? Maybe you can get involved in a group or team with a common objective - an educational or career group, or action committee. Or maybe Toastmasters (about public speaking - many of them start from being afraid of public speaking). I'd suggest getting involved in a group that has a focused purpose other than dieting. And therapy is another option, in addition to support groups.
