What is a sign that a person may need help for a mental disorder?​

Feeling excessively sad or low. Confused thinking or problems concentrating and learning. Extreme mood changes, including uncontrollable “highs” or feelings of euphoria. Prolonged or strong feelings of irritability or anger.

Explanation:

Thoughts like ‘I’m a failure’, ‘It’s my fault’ or ‘I’m worthless’ are all possible signs of a mental health disorder, such as depression. Your friend or loved one may need help if they’re frequently criticising or blaming themselves. When severe, a person may express a feeling to hurt or kill themselves.
