What these are, and are not
These are the same public-domain screening tools GPs and health services use as conversation starters. They are good at one thing: turning a vague sense that something is off into a number you can act on and track over time.
They are not diagnoses, and no result here replaces advice from a doctor or other qualified professional. Everything is scored in your browser: your answers are never sent to us, stored, or attached to your name. If any answer touches on safety, we will show crisis numbers first, because a website is not the right responder for that moment.
