I'd pfind me another therapist.

No real therapist, especially one that
specializes in trauma, could assess -
much less diagnose - within 15 minutes.

Sounds like a hack and a quack to me!

As pfar as art therapy goes for trauma
recovery, I pfound it to be helpful as a
part of my therapy process, but there's
a lot more to trauma recovery than just
drawing stuff ...

Sincerely,
Pfrog!
