A person who does not recognize the signs of a mental illness may not know he needs help

Yes, that is often the case. When someone is unaware of or unable to recognize the signs and symptoms of a mental illness, they may not realize that they need help or that their thoughts, feelings, or behaviors are abnormal. This lack of awareness can prevent them from seeking support and treatment from mental health professionals. It is important to increase mental health awareness and education, so that individuals can identify when they may be experiencing a mental health issue and seek appropriate help.
