Are you some sort of Scientologist or something? Where you think mental illness comes from? It’s not because someone’s trying to be rebellious and show up their parents, and it’s not because people just decide to kill themselves because they heard a Black Sabbath song. Depression is an actual illness which can be actually treated by people who don’t believe in demonic possession or in doing squat-thrusts to overcome biochemical problems; the people who are least likely to get treatment for it as teenagers are those whose parents reject the scientific facts about disease, which happens due to either ignorance, religion, or apathy.
