Question

what does the term \diagnosis\ mean?
to meet with a mental health professional and he or she gives what you are experiencing a name
to be told you have a mental illness
to have a feeling that you know what is wrong
to meet with your medical doctor who gives you a prescription for medication

Explanation:

Diagnosis in the medical and mental health context refers to the process of identifying a disease or disorder. A mental health professional (like a psychiatrist or psychologist) assesses symptoms and gives a name (diagnosis) to what a person is experiencing. For example, in mental health, after evaluating a patient's symptoms, a professional might diagnose depression. The second option is too narrow as diagnosis isn't just about being told one has a mental illness (it's about the naming process). The third option is more of a layman's intuition - like feeling something is wrong but not the formal diagnosis. The fourth option is about getting a prescription (treatment) not diagnosis.

Answer:

To meet with a mental health professional and he or she gives what you are experiencing a name.
