Suggest Treatment For Eating Disorder With Severe Depression

My daughter has been suffering from binge eating disorder and possibly bulimia for six years. She is twenty two. She consumes large quantities of sugary and high carbohydrate food in secret on a regular basis. She had a little general help from a psychologist a year ago but after this was interrupted by an emergency eye operation she did not carry on. She had been suffering severe depression and would sleep, watch videos and secretly eat day after day in University holidays. She went on to self harm. The depression is somewhat better now, and the sleeping has abated during the day. But the eating continues. I am not sure about the self harm. Last January she had a detached retina in one eye and holes in the retina of the other eye and had an emergency scleral buckle operation in one eye and some other treatment in the other. She has poor vision in the scleral buckle eye especially as the pupil has fixed open. Then last summer, the other eye developed a wide open pupil, diagnosed as Adies syndrome. At no time were the doctors informed about her eating patterns (and bulimia). Could her conditions have been affected by the high sugar? Also, last summer she went to her doctor because she felt so tired all the time she felt she had symptoms of ME or CF. She did not tell him about the binge eating of sugar etc and bulimia. He referred her to a specialist hospital clinic for ME which she has just attended. She did not tell them about the binge eating. Do you think her symptoms might be affected by the binge eating? Do you think I should write a secret letter to her doctor (whom I do not know)? She does not want to talk about the issue.
