If you live in England, your local NHS should have a mental health crisis number you can call. To find the number use the NHS urgent mental health helpline finder on the NHS website. You will need to know your postcode. If you live in Wales, you can contact NHS 111 and select option 2. This will put you through to an NHS helpline offering 24/7 urgent mental health support. Visit the NHS 111 Wales website to find out more about this service.
