when i was sent to Elan, i had health issues. they were never addressed nor was there any health care. but, that was 20+ years ago, i do not know of the physical care given now. what i do know, is that my lack of medical help then has caused me life long problems. lyme disease is a difficult auto immune problem that requires genuine medical care.
i honestly do not know enough of the Elan that exists now, but my thought is this:
your child needs help and you know this. if I want you to send your child somewhere please make sure it is a place where you and the child are permitted contact. a place that focuses on the body as well as the mind. a boarding school that you can visit, or where your child is allowed to call you if needed. remove your child from the current environment and the current peer pressure. please avoid any place where communication is denied for months at a time.
auto immune disorders require care. i do not know if Elan is capable or interested in that part. there is no easy answer, it requires a lot of research and as a parent it requires a lot of sacrifice.
i wish you, and your family the best of luck in healing and growing.
please make sure that your child is in a place where medical care is routine, not a place where it is held back as it was in Elan.
good luck, and stay strong for your child.
