The singer celebrated the triumphant occasion with a series of tweets which acknowledged that many who struggle with addiction don’t survive.

“I can’t believe I have 4 years on Tuesday.. Anything is possible,” she tweeted.

“Most people die but others just go.. She’s still out there and the chasm grows.. Steady are the feet in the morning glow.

“This last year I experienced so much life and too much death… But I made it through… Sober. #4Years #GodsWill.”
