Get help now — free helplines

You can call any of these for free. You do not need a diagnosis, an appointment, or a crisis to call — questions and plain exhaustion are reasons enough.

These counts and lists are worked out from the library itself each time the page loads. A score rates how much weight a study can bear — its design, journal, evidence and recency — not whether its result is good news. How we score a study.
