He screamed his lungs out at us, called us every name in the book, has broke everything in the house, laid hands on me, threatened to kill everybody in the family (all of this stuff multiple times), hid knives in his room, pulled knives out on me, swung a baseball bat at my head and argued like crazy, laid hands all of his friends, followed my wife to neighbors house to yell at her etc..( I don't want to give anymore details because it makes me sad). These behaviors are pretty much solely at home except for hitting his friends and getting in minor trouble with the law ( he races cars, and petty crimes such as shoplifting and drug use, trespassing, DUIs and for hitting and threatening us). Hes always had a temper, but it was within normalish bounds. The behavior mentioned above started at 13. He use to bully a little bit in school and got expelled in junior high, both years for bad behavior. By far the most frequent behavior was arguing, yelling and name calling- easily by far. So if your Difficult Child is like mine, what was the diagnoses?
