Thanks everyone. She's had a fairly traumatic two years at college, and the eating disorder resurfaced after she was almost assaulted by a "nice" guy... for the fifth time in a year. She managed to fight him off, but it's been really hard for her to be there around him and around all the other creeps. We are already looking at getting her to talk to a therapist, and we will be probably locking down the food cabinets for a while, so there's less of a temptation to binge. She does have major self-esteem issues (part of the reason she verbally and emotionally abused me for a long time) so we will be very careful about talking about her appearance. She knows I'm always here for her, to talk to, and we are hoping she can get this under control again.
