I am concerned about my friend's child, but have not said anything to her. Her son is 5 years old, and already seems to have some anger-management issues, and seems like a tightly-wound-up little kid. My friend and her husband are supportive of their son (no known abuse in the family or anything).
How do you know when a personality-disorder (or other mental illness) is effecting a person...even as young as 5 years old...vs what is just a more stressed out/Type A child?
