“I’ve been sober sober for the past six months,” the pop star told Variety, adding that the reason behind her lifestyle change  — at first — was “just about this vocal surgery.”

In November, Cyrus, 27, revealed she underwent vocal cord surgery after being hospitalized for tonsillitis. Her recovery consisted of “several weeks of silence.”

But through her sobriety, the “Wrecking Ball” singer discovered in therapy how her parents’ upbringings may have affected her.

“My mom was adopted, and I inherited some of the feelings she had, the abandonment feelings and wanting to prove that you’re wanted and valuable,” she told Variety. “My dad’s parents divorced when he was 3, so my dad raised himself. I did a lot of family history, which has a lot of addiction and mental health challenges.”

Cyrus said that asking herself, “Why am I the way that I am?,” led her to “understand the present and the future much more clearly.”

“I think therapy is great,” she added.

She pointed out that her parents, Billy Ray Cyrus and Tish Cyrus, have not decided to follow her substance-free path.

“One of my favorite interviews is when I say, ‘Anyone that smokes weed is a dummy,’” she said. “That one I love to send to my parents, who are big stoners, every now and then. It’s been really important for me over the last year living a sober lifestyle, because I really wanted to polish up my craft.”

During the coronavirus pandemic, Cyrus hosted a livestream on Instagram with psychiatrist Dr. Daniel Amen, who has helped her overcome her anxiety.

The singer also said being sober has a stigma of being “no fun,” but she said she has learned to deal with the skepticism.

“It’s like, ‘Honey, you can call me a lot of things, but I know that I’m fun,’” she said. “The thing that I love about it is waking up 100%, 100% of the time. I don’t want to wake up feeling groggy. I want to wake up feeling ready.”
