Kevin Love acknowledged he suffered a panic attack during a game in November this season.
Love experienced stomach pain and shortness of breath.
"It came out of nowhere. I'd never had one before," Love wrote in The Players' Tribune. "I didn't even know if they were real. But it was real -- as real a broken hand or a sprained ankle. Since that day, almost everything about the way I think about my mental health has changed."
Love also left a loss at home to the Oklahoma City Thunder in January with what was described as an illness. Love's departure led to an intense team meeting in which his Cleveland teammates challenged the legitimacy of his health.
Sources say Love disclosed to his teammates that he had suffered another panic attack during the loss.
Love wrote that since the initial panic attack he has been seeing a therapist a few times per month.
Love has not played since breaking his hand on Jan. 30th.
