For some people overeating is their preferred form of substance abuse, and substance abuse is often a coping mechanism used against such emotional ills as depression. Those in the counselling biz call this self-medicating. When you remove the coping mechanism without the support of therapy, friends, and the appropriate medication such people can find themselves suddenly feeling very alone and very sad - sad enough to kill themselves. I know a little bit about this because I am a depressive and because of this I have done a lot of reading on the topic.
LBT is a great support group and does assist us with coping with the loss of the comfort of food as well as with weight loss. I know that this group has certainly helped me during my year of weight loss and continues to help me now that I am at goal. :ranger:
