The Samaritans/Befrienders

The Samaritans are a charity based in the United Kingdom and Republic of Ireland, which provides awareness for people that are in crisis at risk for suicide.
They are primarily based in the UK and Ireland, with resources such as a telephone helpline. For the world outside of the UK and Ireland, befrienders.org is also a great online resources for help and crisis intervention numbers.
Since 1994 the charity has provided support for people worldwide in crisis by e-mail, but do not give advise and do not consider themselves a counseling service. They are a "listening needs" for those who just simply need to express their frustrations and what their crisis may be.
They have a code of confidentiality except in rare cases where other types of intervention may be needed.
Due to the rise and use of the internet, their work has extended beyond the UK and now are found in over 400 countries worldwide providing awareness for those that may be in crisis.
Personally, I have used the e-mail service they provide and usually try to respond within 24 hours. They provided a wonderful, confidential service when I was in need.

"A society in which: fewer people die by suicide; people are able to explore their feelings; people are able to acknowledge and respect the feelings of others."
