"Support systems are extremely important, and your sister, Ruth, has been kind of your sole support system," Dr. Saltz says. "And because of these mixed feelings, that is not really a great way to go. You can love each other, and I would say you [Ruth] could help her. Not with the food, where you have these mixed feelings, but give her time. Maybe be with her sons so she has some time to take a walk or to do some things that feel more healthful for her. Until you can be more aware of what you're saying about food and about your mixed feelings, you [Mary] need some friends, some community, some people around you who can really support you, because they're not invested in this relationship."
