Help autistic teen obtain mental health treatment

Our autistic child has been struggling with several mental health issues. During the COVID shutdown his access to treatment decreased and his symptoms were exacerbated, eventually leading to 2 acute hospitalizations. His symptoms have become severe enough that his treatment team has recommended a more long term residential program. The cost of the 9 month residential program is not covered by our insurance and totals around $72,000. Any help toward getting our son the help he requires would be greatly appreciated.
