Hi
Just to let you know, I wish I could help you too. It's a really tough sitiation you're in with your daughter.
I'm a physio and worked at a psychiatric hospital where girls with eating disorders were admitted. I worked as part of a team with psychiatrists, dietitians etc, but really the dietician played a small part. The girls often knew exactly the number of calories in any given amount of any food. The physiotherapy helped them with body image, and body perception. Many of them love working out (to loose weight, obviously) so we'd encourage them to use their body in a beneficial way, and to feel what goes on in the body when they use it. Many also suffer from anxiety and many of the physical symptoms here are the same as with exercise. Sweating, pulse up etc. Anyway, just letting you know that there's many professions that can help, but I don't think just one has the answer. It really needs to be a combined effort. Re. costs, maybe Centrelink could help?
Also, DON?T stop talking to her about sex. If she hasn't had sex already, she probably will within the next couple of years and it's so important that she knows you're there to talk to. Tell her that you'll never be angry or dissapointed in her, whatever she has done, then she'll be more likely to come to you, even if she knows she's done something less fortunate...
Please don't stop writing in here if that helps you, I'm sure there's quite a few of us that'll try to help you out.
If you haven't googled it, I'm sure there'll be a plethora of chatrooms out there for parents with kids with eating disorders, that might help too?
All the best
Christine

Go mum!
