Mr Donald Trump's shock victory in the presidential election last Tuesday has prompted several thousands of Americans to stage protests across the country.

Some have chosen to go underground to vent their anger and frustration - as in this New York subway initiative.

Commuters have been indulging in collective therapy - writing messages on Post-it notes and sticking them on a subway wall.

"Am I the only one who is scared?" "I need a hug" and "I am angry" are among the thousands of messages written on multi- coloured squares of paper pasted on a wall at Union Square station.

Mr Matthew Chavez, 28, a bartender from Brooklyn, came up with the "subway therapy" idea, setting up a table piled with the sticky notes the day after the election for people to release their anxieties. And within 24 hours, there were 3,000 notes.

"It's great," 33-year-old New Yorker Andrea Recarte told Agence France-Presse. "He is giving us an opportunity to word it. It connects us with many other people who are speechless."
