"I am married with a wonderful son, but am so in love with an ex-partner that my heart feels dead," an anonymous commuter revealed on Brighton's Waiting Wall.
The wall is a new initiative launched as part of the city's digital festival.
Although it is a temporary feature intended to mirror Jerusalem's Wailing Wall, it gives commuters a window of opportunity to air their deepest and darkest thoughts without giving away their identity.
The display, which runs from September 21 to September 27, was inspired by author and philosopher Alain de Botton.

The messages that have been posted so far range from deeply personal stories to general musings about life.
