The overdose, reportedly of opioids laced with fentanyl, came a month after she had broken six years of sobriety.
Speaking to journalists this week, she revealed the lasting effects the episode has had.
“I don’t drive a car because I have blind spots in my vision,” she said.
“For a long time, I had a really hard time reading. It was a big deal when I was able to read a book, which was like two months later, because my vision was so blurry.”
