I'm glad you have a sense of humor because that seems like one of the helpful reactions that could arise from such a nightmare.

It's remarkable how institutions (the school psychologist in your case) often re-inflict the trauma that is going on at home. It's their job to protect the child, but often they do the opposite, and it's worth asking why. I experienced this myself, though in a very different context—everyone's story is unique of course.
Good for you for surviving, and best wishes for growth and healing.
