How Harry didn't need intense counselling after this ordeal is staggering. The eleven year old boy has come face to face (or back of head to face) with the most powerful Dark Wizard of all time. Not only is Voldemort living on the back of a trusted teacher's head, but Harry is staring into the eyes of the person who is responsible for the murder of his parents. As we all know, it's love that becomes a weapon at this point. Lily's love and protection of Harry is embedded in his skin making him able to defend himself against Quirrell. But by burning his face off and then turning him into dust. Although Harry collapses after this battle, he doesn't really show any trauma suffered by this confrontation, but he's happier at the fact that he now has lots of free sweets.
