Thank you all for your generous support, as usual!
I posted cuz I wanted to get a feel from folks out there, and I got the 'feel'...
I also emailed to the NYPD and they advised me not to report my son. They made other good suggestions.
In the meantime, I wrote to his previous therapist and she responded to my letter. She maintains that she has valid reasons for terminating him but that my letter has moved her and she is willing to take a chance on seeing him again. I am elated! Ecstatic! Overjoyed! Relieved! Hopeful! I hope she gets her just reward for this huge act of kindness.

Just wanted to update you all! Thanks again!
