In Serbia over 1500 persons take their own lives per year, with 40 people jumping of the Belgrade Bridges. To prevent these people for killing themselves, the organization Suicide Prevention Office has been set up, where unhappy people can speak to specialists.
The only thing is, not everybody calls them. that is why they put a message for these people on a rather special place.. On the bridge.
The projected message and phone number can be seen when looking down from the bridge only.
