If you broke your arm, you'd go to a doctor. Why not go to a doctor, if you have a mental illness? You go to a dentist for preventative care. Why don't you go to therapy for preventative care? The problem is that people see their body as a separate part of them from their mind. The mind is a symbol of their sense of self. If something happens to their body, they get it fixed. If something happens to their mind, they feel like they are broken as a person and are permanently damaged. If they sprain their arm, they say, "my arm is sprained". If they are depressed, they say, "I'm depressed".
