I am sorry that these problems just seem to be compounding for you and your family. In a way, I agree with your daughter's doctor. Isolating her is like a punishment. Instead, they should isolate the bullies, take away their privileges so that Mikela can go outside and play and enjoy herself without the threat of being harassed. If they want to keep her away, then they should allow her to do something that makes her feel special, not alone!
You mention that you are all living in one room now. I must have missed some of your posts, so forgive me for probably asking questions that you've already answered. Are you now living somewhere else? Is this temporary? I am hoping that it is and that your new housing is going to be available very soon.
I am keeping you, as always, in my prayers. Sending you warm hugs.
Peace and Blessings
Look For The Good and Praise It!
