The police are not a health service but will respond when appropriate to prevent harm where there are immediate risks to the person or others. Officers attending would seek to get anyone involved safe and then signpost to the most appropriate services.
Below is a list of some of the services available to you:
GP – You should book an appointment through your GP if you can
24-hour crisis line can help if you are in a crisis at any time – 0808 196 3779
