WASHINGTON (AP) - Sen. John Fetterman acknowledges having “dark conversations” about harming himself before he hit “the emergency brake” and sought treatment for depression.

He remembers thinking about his three school-age kids. “I can’t be a blueprint for my children. I can’t let them be left alone or not to understand why he would have done that,” the first-term Pennsylvania Democrat told NBC’s “Meet the Press” in a deeply personal and introspective interview taped before the broadcast that aired Sunday.

So he checked himself into Walter Reed National Military Medical Center in Bethesda, Maryland, last Feb. 15. “There was nowhere else to go,” he said, describing how he often felt during his stay that “there wasn’t any hope sometimes and like, ‘What do I have left?’”

He also wondered whether he would survive politically.

“When it got released where I was and where it was going, it was a big story. And so, I had assumed that that would be the end of my career,” he said

When he sought treatment for clinical depression, Fetterman was still coping with the effects of the stroke he had in May 2022, during his campaign for one of the Senate’s most contested seats. “My heart technically stopped, and it was a very touch-and-go situation,” said Fetterman, 54. A pacemaker was implanted with a defibrillator to manage two heart conditions, atrial fibrillation and cardiomyopathy.

His victory over Republican Mehmet Oz had helped Democrats keep control of the Senate and made him a national figure. It was the height of his political career. But he couldn’t make it out of bed at his home in Braddock, in western Pennsylvania.

Within two months, he was at Walter Reed. Aides had described the new senator as being withdrawn and uninterested in eating, discussing work or the usual banter with staff.

Before checking into Walter Reed, Fetterman had never publicly discussed his battle with depression. He has since said that he has experienced it on and off throughout his life.

He left Walter Reed at the end of March after six weeks of inpatient treatment with his depression “in remission,” according to a statement from his office.

Doctors describe “remission” as when a patient responds to treatment so that they have returned to normal social function and they are indistinguishable from someone who has never had depression.

Fetterman has since become a visible presence in the Capitol, bantering with reporters, joking with Senate colleagues and speaking up at Senate hearings.

To others who are now “facing a really dark holiday time,” Fetterman offered this guidance: “I know that last year’s was desolate. And this year’s might be desolate. Next year’s can be the best ever. And that’s what happened for me.”
