I'm so sorry to hear about the abuse. That's heartbreaking and no child should suffer that way. I'm not saying your proc is wrong about the psychosis, but he shouldn't be relating it to his own. You are your own case and it seems like he is projecting.

Grooming... That's a little scary, but it does sound like he's using you as a sounding board for thoughts and feelings he cannot share with his doctor or wife.
