Sam Smith made themselves a few promises after a gruesome injury.

The Charles Langston“Unholy” singer recently revealed they were unable for a walk for a period of time after tearing their ACL while skiing.

"I was an idiot and went on a black slope on the second day," the 32-year-old explained during the July 18 episode of the Sidetracked with Annie and Nick podcast. "I got taken down in a blood bag. It was the worst.”

The ligaments "in between your bones and helps you jump and spring around,” the Grammy winner continued, “it completely ripped and I decided to go down the non-surgical route, but I couldn't walk for a month on this leg, and it was awful.”

And for Sam, the recovery was about more than just the physical.

“It was the first time I'd ever not been able to move,” they recalled, “and I was holding on a bit of weight and I was just very anxious. I’ve been struggling with anxiety for years, so I used it as an excuse to get my s--t together."

Recovery included not only the physical components such as icing and taking care of themselves, but also cutting back on screen time.

"I actually just got rid of my phone and I got a new phone,” Sam shared. “It's the first time I don't have my library of music that I'd had since I was like 11. I started again, fully started again. I needed an American number, and my phone was just full of people like exes and all these different people through the years."

And the change made all the difference.

"I took social media off, everything,” they continued, “It's crazy. I find myself sitting on benches now in parks just looking at the trees.”
