Would a person with mental health problem be aware that they have problem?

Not necessarily. Lack of insight into one's mental health condition is a common symptom of certain psychiatric disorders. For example, individuals with schizophrenia or delusions may not recognize that their thoughts or beliefs are unusual or irrational. Insight can be affected by various factors, including the type of mental illness, severity, and personal characteristics. Some individuals may have limited self-awareness due to impaired cognitive function or difficulties in processing and interpreting information. It is essential for mental health professionals to assess insight when evaluating and treating individuals with mental health problems.
