President-elect Donald Trump is driving New Yorkers crazy.

Anxiety is so high in the Big Apple following Trump’s astonishing presidential win that patients are rushing to their therapists to book emergency therapy sessions.

Dr. Chloe Carmichael, a clinical psychologist and stress management expert based in Manhattan, said she was already swamped at 6:30 a.m. Wednesday helping her clients navigate their emotions surrounding the election’s results.

“It was something that came up immediately,” she told The Post.

And it wasn’t just Carmichael’s existing patients who needed someone to talk to about the 2016 race.

“We did get a couple of calls from new clients who want to come in because they’re disappointed, very sad or honestly even really happy,” Carmichael said.

Midtown psychologist Bruce Berman said one of his gay patients needed to come in immediately.

“He was worried about what this was going to mean for him and other gay people,” Berman said. “His worry is that they’re going to roll back rights. He was also concerned about an increase in anti-gay violence.”

Berman said he’s not surprised city dwellers were having a hard time stomaching the reality of a Trump presidency.

“Certainly it’s expected in New York City because it is quite liberal,” he said. “It’s an outcome that is leaving people frightened, disappointed and somewhat grief-stricken.”

Even New York University distributed a memo to its students that offered various counseling and mental health hotlines for those feeling “scared, hopeless, or just in need of someone to talk to.”

“Reaching out is not shameful. If this week has been too much to handle, these resources are free and confidential,” the memo said.

Carmichael said it will take at least a week for people to get to the acceptance stage of their grief regarding the election — and that some may have relapses and bouts of high anxiety as it gets closer to Trump’s inauguration day in January.

But she encouraged those who feel helpless and sad to “counteract those feelings” by doing good — volunteering or having a positive influence on something they care about.

Those who are feeling angry can also use it to their benefit by exercising or working regular walks into their daily routines.

“Anger is a feeling that is usually accompanied by energy. So when we get angry, we clench our fists and we get a little heat — that’s Mother Nature’s way of helping us take action when we’re confronted with some kind of injustice,” Carmichael said.

And while she has her fair share of disgruntled clients, Carmichael, whose practice is located on Park Avenue, said she has a slew of regulars who are predominantly from the financial industry who are ecstatic about Trump’s win.

“People can find it more difficult to talk about politics than sex because it’s such a taboo to talk about, especially if you’re on the conservative side,” she said. “They’re so afraid of being ostracized.”
