Have you tried Weight Watchers? There may be a meeting for that closer to you.

You probably do need couseling to help you overcome the reasons behind why you eat so much. My Dad also used to be an eat everything on your plate sort guy. It took a long time for me to realize that I don't have to finish every bite, but still the thought goes through my mind everytime I eat, especially, when I eat out.

I hope you find the help you need. I wish there was an easy solution for you, but it's really up to you in the end. I do hope you get the support you need. I'm sorry your family is not providing this. It is sad they won't help.
