it's great that your friend is willing ot seek help, and too bad you're so far away. That must be hard on you, feeling as though you can't do much.

What you can do is to help her find resources, and to do taht, you have to find some. Here's a starter kit for you:

http://www.somethingfishy.org
they've got great resources, including searchable referrals

http://www.anad.org
they've got peer support groups that can be helpful, although not a substitute for professional help.

http://www.edreferral.com
just what it sounds like, referrals for eating disorders.

Overeaters Anonymous is the 12-step that most people go to, if they want a 12 step program. I don't find 12-steps helpful, and know that many other people with EDs don't, either. We already know we're powerless over food...

Also some books that might be helpful, like Bulimia Nervosa, by Lindsay Hall. There are also numerous self help workbooks that can help, and you can find most of them at Gurze Books, which you can find online at http://www.gurze.com/ Gurze is a great resource, just in general, if you want information about eating disorders.

Aside from doctors for your friend, which will be very hard, another avenue to direct her to, as an adjunct to, and not instead of, therapy, is nutritional counseling. She'll want to see a Registered Dietitian, not just a nutritionist. Get the one with the proper credential, and see if it's someone with some training in EDs.

Finding a therapist who treats eating disorders is awfully hard. How old is yoru friend? If she's younger, she'll have many more resources out there. Many therapists don't like to see adults with EDs, because they assume it's long standing. (It usually is, of course.) While you can look for a Certified Eating Disordes Specialist, they're rare on the ground. Many other therapists, though, can help. While I always think that psychodynamic therapy is the best bet, for bulimia there have been good results (short term, at least) with CBT and even modified DBT. But she should know that those are not the only options. If she tries CBT, say, and does well -- but finds herself purging again after six months, that doesn't mean that she won't benefit from another form of therapy. (Or even just another therapist...)

Good luck, and feel free to ask any questions. I can try to answer. You can also PM me, if you don't hear back from me here.
