Sigh.
I am sorry that the PO doesn't believe in mental health issues. Grrr.
But I like RMom's idea, that your son will get Residential Treatment Center (RTC) eventually when a bed is available. It could all work out in the end, as convoluted as it has been.
I hope difficult child gets the mental health care he needs in juvie after the evaluation. I've got my fingers crossed.
