Dorset Community Action have included a very useful new leaflet in their resources to help organisations, family and friends. This is produced by Prevent Suicide (http://www.prevent-suicide.org.uk) and is a concise summary of useful information.
Please have a read as you never know when it might be useful, think of it a bit like learning First Aid.
