Jessica Simpson said that her new release, a song about addiction, helped to "heal her."

Simpson released a cover of "Particles" by Nothing But Thieves on Thursday.

"The whole idea of music heals is a very real statement to me. This song healed a broken piece of me," the pop star wrote in the description of the video uploaded to YouTube.

In a Twitter thread posted earlier this month, Simpson shared a photo of herself from when she was living with addiction in 2017.

"I had so much self discovery to unlock and explore," she wrote of her past self.

"I can't believe it has been 4yrs! It feels like maybe 2," she added, referencing how many years she has been sober.

Simpson said she learned to "allow myself to take back my light, show victory over my internal battle of self-respect, and brave this world with piercing clarity."

"The drinking wasn't the issue. I was. I didn't love myself. I didn't respect my own power. Today I do," she added.

She concluded: "I am free."
