Our son threatened sucide when he was 14 1/2 years old. I made an appt. for him to be evaluated by a Neurologist at the Cleveland Clinic. The day they evaluated him, they kept him for 7 weeks.
NEVER during all that time did they ever drug test him.
His discharge diagnosis was "Adolescent Adjustment Disorder" seriously.
Sent him home on an antidepressant for a few weeks.
I, at the time was having a "ADULT adjustment disorder"
(I still have it....somedays...)
It was, for him, a missed opportunity.
