New Yorkers are venting their post-election fury on Post-it notes as part of a massive art installation at the Union Square subway station.

Artist Mathew Chavez set “Subway Therapy” up on Wednesday night and Thursday afternoon, encouraging riders to take a moment to write their feelings down and post them on the wall.

The experiment led to thousands of messages on the wall, including “love always trumps hate,” “I’m living for love. I’m GAY and proud of it,” and “we are more alike than we think.”

Chavez said he started the project to help people express their raw feelings.

“I thought it was going to be a really stressful couple of days,” said Chavez. “It has been and it’s probably going to keep being stressful and I want to make people smile and laugh and feel less stressed.”

Chavez set up a small, grey table with two wooden chairs and laid out packs of multi-colored post-its and pens. Riders clamored to write down their messages, take photos, and read what was written. Someone walked by at one point and screamed “F— Trump.”

The artist and his crew collected more than 2,000 messages on Wednesday and were well on that way to that many again on Thursday, said Adam Shorr, 27, who is Chavez’s best friend. They take them down when they leave at the end of the night.

“He took it down because he didn’t want it to be defaced and disrupt the people who clean the tunnels.” said Shorr.

Straphangers looked solemn and emotional as they read the messages and added theirs to the wall.

“It was my first chance to think or breathe all day, and I let go,” said Sarah Outhwaite, who wrote “Thanks for writing” on a hot pink post-it note. “It felt like a memorial – not like an interactive installation.”

Bridgette Moore, 29, wrote the message “Disappointed and ashamed. we can do do better than this.”

“It’s an amazing he and the people created this,” said Moore. “To live here and see it happen is scary. He is a bigot, racist, sexist, and holding one of the most powerful positions in the world.”

Chavez has been working on the Subway Therapy project for six months, but it blew up after the presidential election on Tuesday night.

“After the election, I thought there would be a lot of people upset and maybe having a conversation they were unable to do because they just couldn’t so I wanted to give people an opportunity to write something down on a small piece of paper so people can get something off their chest quickly and just walk away,” he said. “It’s been really successful.”
