Taylor Swift has had a massive year, and now the pop star is opening up about her road to success — and all the bumps along the way.

In a rare interview with Time as she’s crowned the publication’s Person of the Year, Swift celebrated what she feels is the “breakthrough moment” of her career after her record-shattering Eras Tour and highly successful concert film.

I’ve been raised up and down the flagpole of public opinion so many times in the last 20 years,” Swift told Time. “I’ve been given a tiara, then had it taken away. It feels like the breakthrough moment of my career, happening at 33. And for the first time in my life, I was mentally tough enough to take what comes with that.

However, Swift said it took reaching her lowest point to truly appreciate this high. “It’s not lost on me that the two great catalysts for this happening were two horrendous things that happened to me,” she said. “The first was getting canceled within an inch of my life and sanity. The second was having my life’s work taken away from me by someone who hates me.”

Swift is referring in part to her public feud with Kanye West and Kim Kardashian that led to her “Reputation” era. In 2016, West released the song “Famous,” in which he infamously rapped the line “I made that bitch famous,” and claimed that Swift had consented to it, which she denied. Kim Kardashian, West’s then-wife, leaked a recording of a phone call between West and Swift in which the singer seemed to have approved the line, but a longer version of the video showed that she had not. Swift told Time that in the moment, it felt like a “career death.”

You have a fully manufactured frame job, in an illegally recorded phone call, which Kim Kardashian edited and then put out to say to everyone that I was a liar,” Swift said. “That took me down psychologically to a place I’ve never been before. I moved to a foreign country. I didn’t leave a rental house for a year. I was afraid to get on phone calls. I pushed away most people in my life because I didn’t trust anyone anymore. I went down really, really hard.”

After the release of her “Reputation” follow-up “Lover,” Swift was struck down once again — this time by the sale of her catalog from Big Machine’s Scott Borchetta to managing mogul Scooter Braun. “With the Scooter thing, my masters were being sold to someone who actively wanted them for nefarious reasons, in my opinion,” Swift told Time. “I was so knocked on my ass by the sale of my music, and to whom it was sold. I was like, ‘Oh, they got me beat now. This is it. I don’t know what to do.’”
