This is the reverse side of a British rail ticket. As you can see there is an advert by the Samaritans which is a registered British charity with the aim of helping people when they are going through a particularly bad time. These people may be feeling lonely, helpless, worthless and as if no-one cares. People do care and are willing to listen and try to help you. All you have to do is to reach out and make a telephone call or speak to a person you trust.
The Samaritans website says:
We offer a safe place for you to talk any time you like, in your own way - about whatever's getting to you
We're here round the clock
Whoever you are, however you feel, whatever life's done to you
We're not a religious organisation
