How assessment may be approached
A qualified clinician may ask about mood, anxiety, sleep, appetite, functioning, medicines, substances, trauma, physical contributors and personal safety. Assessment is private and aims to understand the pattern before naming a diagnosis.
Options may include psychotherapy, practical support, treatment of contributors, medication when clinically appropriate, safety planning and follow-up. Do not stop prescribed psychiatric medicine without the prescriber's advice.
When to seek prompt care
Seek immediate local emergency or trusted-person support for thoughts, intent or plans of self-harm or harming others, severe agitation, inability to stay safe, psychosis, severe intoxication or inability to meet basic needs.
