The event, the latest edition of a conversation series called Get With The Times, was shown live and broadcast to watch parties held on college campuses across the country.

“I really truly believe that everybody is going through something,” he said, echoing what he wrote in a deeply personal essay in The Players’ Tribune in March, several months after the panic attack.

Since the publication of his essay, Love has emerged as a high-profile voice on the topic of mental health. Around the same time as the essay, another player, DeMar DeRozan, who then played for the Toronto Raptors, spoke out about his depression. Several other players have discussed their mental health struggles, and in May, the N.B.A. appointed its first director of mental health.

Though Love said Thursday that he was initially uneasy about how his article would be received, thousands of positive emails came pouring in; he heard from close friends who were deeply affected; and employees of other teams have pulled him aside to say they are glad he got the conversation started.

“The biggest thing in my 11-year career so far that I’ve done has been this,” he said.

And as for how his teammates would react? Love said he was on a bus with his team in Denver soon after the essay was published when his former teammate Kyle Korver immediately told him he wanted to find a way to help. As the team walked off the bus, Love said, LeBron James — who has poured money and time into various charitable endeavors — pulled Love aside, shook his hand and said, “Today you helped a lot of people.”
