Hi there ~
I understand you situation and it seems to me that you are trying your best to help this young lady. I hope you have consulted a psychiatrist
already. There is cure for the condition and you should take the advise seriously. Management of her condition should not be an issue in special education. I would think that there would be some residual damage that cannot be reversed but there have been miracles. Please do not give up. I hope this helps.
Take care and have a lovely day!
