PTSD Presents in Many Forms

I have a child one month from 16, female believes she was born in the wrong body, should have been a boy. Has never been able to form friendships unless online. Always depressed diagnosed with ADHD, PTSD, very smart but exhibits some autistic symptoms soon to be tested. Genetic testing done with no abnormal findings. Trauma brain testing just dome. She was born with bi-lateral cleft pallet which is in process of being corrected but has been halted surgeries because of her emotional state until she is stabilized. The school and local mental health facility whom failed in motivating her to engage in any group or individual talk therapy and after fighting with them has agreed that residential treatment is needed. I would like to know what recommendation you may have for treatment in New England.
