"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.

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