A mental illness or mental disorder was a psychological condition in which a person may have behaved in a somewhat inappropriate manner, be harmful to themselves or others, or found themselves obsessive or addicted to something.
One could acquire a mental illness from birth, such as autism or ADHD, or from trauma, such as PTSD or Stockholm Syndrome, whether due to physical or mental trauma.
