Nick Cannon, who's long lived with lupus, was recently hospitalized with pneumonia. He revealed the news on Instagram, along with a reminder to others to take care of their health.

“Okay, so I guess I’m not Superman,” Cannon wrote. “I promised myself I would never be back at this place again…But this is a great lesson to take care of YOU or YOU won’t be able to take care of everyone else.”

According to Nick, he went from "rocking a sold out crowd at Madison square garden in front of thousands of fans" as part of his Wild ‘N Out tour to being "all alone in a tiny hospital room." He noted that he doesn't "need any well wishes or prayers" and assured that he'd be fine with "some solid rest," adding, "I will be back on the journey to becoming stronger than ever.”

“It’s just pneumonia, nothing I can’t handle," he concluded.

While Nick physically recovers, he admits he's been struggling mentally and spiritually. The actor's son Zen passed away a year ago on December 5 following a battle with brain cancer. "Been tossing and turning all night, and as much as I know I need rest, last night I couldn't sleep at all," he wrote in a tribute honoring his late son's death anniversary. "I can't believe it's been a year already since the toughest day of my life occurred. Such a painful anniversary."

"Losing a child has to be the heaviest, most dark and depressive experiences that I will never get over," he said. "A mixture of guilt, pain, and sorrow is what I suppress daily."

Nick added, "...I love with my entire Heart and Soul and I just wish my Little Man could've felt more of that love while he was here on Earth."
