Cameron Kasky doesn’t want your sympathy.

“Sympathy bugs the hell out of me because I feel such an imposter syndrome,” he said. “So many people went through so much more than I did.”

On Feb. 14, 2018, Kasky’s life changed forever after a gunman stormed into Marjory Stoneman Douglas High School in Parkland, Florida, killing 17 people, and wounding 17 more.

“I was a lot farther than a lot of kids who were able to come back to school,” the nationally-known gun-control activist said, recalling the carnage but adding how lucky he had been to be out of the line of fire. “There were kids who walked out of school that day who saw people die with their very eyes.”

“Kids who saw it with their own eyes — unlike me — they’re still f–king going to school today.”

Kasky, 18, never finished high school. Shortly after the bloodshed, he dropped out to travel the country agitating for changes in gun laws. He eventually completed a GED.

On Wednesday, he joins the Ivy League. That’s when classes start on the Morningside Heights campus of Columbia University.

In between long swigs of Diet Coke in his off-campus apartment, the teenager told The Post he is already in love with the Big Apple.

A longtime theater fan, he’s looking forward to taking in some Broadway soon — and is particularly excited for “Hadestown.”

Kasky, who’s been in town for a few weeks, is fond of dining at financier-politico Anthony Scaramucci’s Hunt & Fish Club, which he often visits with the Mooch’s son, Anthony Scaramucci Jr. (who also goes by The Mooch). Kasky described Mooch Jr as his “BFF.” The two met through a mutual friend, actor David Mazouz, who spent five seasons playing Bruce Wayne on the hit show “Gotham.”

Kasky also has an interest in Hizzoner. He meticulously follows the 2020 Democratic candidates and calls Bill de Blasio’s presidential run “a joke” and “disaster.” “I want to meet de Blasio. I want to see if I can keep a straight face,” he laughed.

But he is serious about the academic path ahead of him.

“I am nervous about how excited I am. It’s just so bizarre for me. I am giddy to get into class,” he told The Post. On deck for the first semester: African American music studies, intro to human rights, masterpieces of western art, and a writing class.

“I want to major in human rights,” he said. “Human rights is wide enough of a range that I feel like I can apply it in a lot of different fields. It’s something that means a lot to me.”

“When you go to a school like Columbia, you owe it to the world to use that knowledge to make the world a better place,” he added. He’s not sure what he wants to do after graduation, but says he has a passion for screen- and stage-writing and never wants to get too far from activism.

Along with fellow students Emma González and David Hogg, Kasky co-founded the March for Our Lives movement dedicated to eradicating gun violence in America. Kasky helped organize the group’s march on Washington in March 2018, which — along with concurrent rallies around the country — drew more than 2 million people.

He left the group in September 2018 because of the strain it was putting on his mental health. Kasky has battled ADHD and bipolar disorder for much of his life.

“It’s hard to be part of that kind of organization for too long without burning out,” he said. “I found myself at a point where I was rapidly cycling with my bipolar disorder, not completely aware it was happening, not medicating, not being honest with myself about my mental health.”

Kasky frequently speaks about his struggles with mental health to his more than half a million Twitter followers.

“Hey, to all bipolar students starting college that don’t know whether their mix of unbelievable excitement and horrible dread is bipolar disorder or starting college. It’s both I think. And it is WHAAAAACK. I’m here with you. We will live. Lol,” he posted earlier this week. “Just for god’s sake don’t forget to take your meds.”

While Kasky says the Parkland tragedy will always be a part of his life, and notes that he isn’t necessarily living in the safest neighborhood in New York City, he doesn’t worry about gun violence on campus or anywhere else in town.

“I feel safe at Columbia,” he said, “I feel safe in New York City.”
