Depression UK is a national Self Help Organisation that offers support to its several hundred members. Most suffer from depression; others may be past sufferers, or care for those who have the illness.
They also provide information, produce a quarterly newsletter and run a pen friend scheme (plus telephone and online chat equivalents). Their volunteers try to respond to enquiries within a few days, holiday and other commitments permitting. Any packs of information they may send to you are posted out under plain cover.
Depression UK run a membership scheme and a number of services are limited to members only (see website for more details).
