You deserve to have support around these painful feelings. It may also be important somewhere in the course of your child's recovery for you to investigate certain aspects of yourself. For example, you may need to examine the ways you communicate and the roles you have played in the past as well as in the present. You may need to explore your own views of food, weight, dieting, and body image and how these views may be influential to her. These issues are certain to arise if you are involved in family therapy.
Family therapy can be extraordinarily beneficial for everyone involved.
It is a good place to explore and resolve communication problems, improve strained relations, and work out hurt feelings. Family therapy tends to be most helpful when all family members agree to look honestly and openly at any and all problem areas existing within the family's dynamics. Avoid commenting on her looks. If you say she is too thin that will only please her, because that is her goal. If you tell her she looks 'good' she will invariably interpret that to mean that she looks fat, therefore, this statement is likely to only further fuel her attempts to lose weight.
