What should children do if they are afraid of mental illness after seeing Charles IX?

See a psychiatrist and reflect on whether your child has done anything before that will make him feel guilty, or whether he has any psychological shadow. The causes of mental illness are very complicated, just like you won't be scared by a simple horror movie, but you will be reminded of your guilt by the pictures of three people in it. A child who grew up in a healthy environment can be said to be innocent. Three people won't induce his guilt. Ignorance is fearless, and newborn calves are not afraid of tigers. I don't need to teach you this.
