In an interview with People, retired Canadian-American actor Michael J. Fox opened up about his darkest life moments. He revealed that the nightmare period was in 2018 after being diagnosed with a spinal tumor.

After the tumor was excised, Fox again broke his arm in a fall while still having a personal battle with Parkinson’s disease. The “Back To The Future” star has always been candid about his Parkinson’s disease for decades, but his other two health challenges were kept a secret.

In the interview, Fox revealed that the excruciating non-cancerous spinal tumor almost resulted in paralysis for him.

The author and film producer plugged his upcoming memoir “No Time Like The Future” when he was on the People magazine cover.

He opened up about his health crisis and explained that the tumor was constricting his spinal cord, so it had to be carefully removed, so it doesn’t cause further damage.

He continued and shared that it took him four months post-surgery to regain the ability to work again, but he finally feels he’s on his way to recovery. The “Boston Legal” star was in his New York apartment alone after a family vacation when he broke his arm while taking a tumble in the kitchen.

Before the kitchen accident, Fox had dashed into New York, leaving his family on their vacation to “Martha’s Vineyard” to shoot a cameo for Spike Lee, which he was unable to do due to his injury the morning he was scheduled for the gig.

Fox shared the moment he snapped, and his darkest moment as he waited for the ambulance to arrive flashed before his eyes.

At that moment, Fox disclosed that he knew there was no bright side to the moment, as he only felt regret and pain all over.

The “Curb Your Enthusiasm” star revealed that his low spirits made him feel like a fraud and the wrong man to have been promoting an upbeat attitude to his fans.

He added that although his battle with Parkinson’s, the spinal tumor, and his broken arm does not compare to others’ misery, he still couldn’t tell others in good faith to look on the bright side of things.

However, Fox got his happy self back while recuperating in bed and watching old TV game shows from the 1970s.

The 59-year-old said, “Optimism is rooted in gratitude,” as optimism is achievable when you can be grateful, followed by acceptance.

He continued that accepting what has happened for what it did not mean that you can’t endeavor to change the narrative or that you have to accept it as a punishment, but accepting it allows you to move on and thrive in life.

He finished by saying that although he had always been sincere, his gratitude is more profound now, having experienced the darkest times.
