Ann Jillian went from a Disney child star to a ’80s sitcom favorite, even portraying her own battle with cancer on screen. Then, at the height of her career, she walked away from Hollywood. The actress, who won a Golden Globe in 1989 for the TV movie “The Ann Jillian Story,” recently appeared on the podcast  “Famous with Jacy Dawn Valeras”  to discuss leaving showbiz at the peak of her career. “I’ve been out of it for a while,” said the 76-year-old. “I’ve been out of it for a good reason. I gave birth to my one and only son when I was 42, and I took that seriously too. “Now, maybe somebody out there can do this, and good for them,” she said, speaking about balancing both motherhood and fame. “I love that they can. For me, I recognize that I cannot. Since I like to focus on what I do, I cannot do all things at the same time.
