Make it a public critique, not just of the prof but of the whole freaking school. Toss in mentions of intentional infliction of emotional distress.
Even better, analogize to your situation.
"A may have a cause of action against B for negligent infliction of emotional distress, similar to the cause of action a student could file against a law school for putting it in the 'zone of danger' of having a nervous breakdown. The zone of danger test works like this: when one party causes death or serious injury to another (i.e. a nervous breakdown) and someone close to that person reasonably believes they are in danger as a result of the original tortfeasor's (i.e. the law school) actions. A can hope to recover money damages, but a law school student should seek an injunction against the school to stop it from causing harm to other students. In balancing the equities, the court will likely find this is necessary."
Can you tell I'm sick of studying?
