Sharon Stone's Children Were the Reason She Kept Fighting During Her Most Difficult Years

The 'Agent X' star opened up to ET about her struggle to recover after suffering a stroke in 2001, and losing custody of her son Roan.

In 2001, actress Sharon Stone suffered a stroke and subsequent brain hemorrhage, and just a few short years later she got divorced from journalist Phil Bronstein, and lost custody of her son Roan.

Over a decade later
, Stone is starring in the upcoming TNT action drama Agent X, and has several feature films currently in the works.

On Tuesday, Stone spoke with ET at the premiere of Agent X in West Hollywood, and the 57-year-old star got candid about what kept her fighting during such a difficult time.

"My children. They really look to me and they really depended on me," Stone said of her three adopted sons, Roan, Laird and Quinn. "I also had a child I was raising from far away that I lost custody of in the beginning, when I really wasn't and probably shouldn't have been in court. But that's what I had to do. So the fact that I was trying to parent long distance was something that really kept me together."

"It was hard, but ultimately it was really those lessons that are always really good and it helped me," Stone added.

Thankfully, these days, the Oscar-nominated star is looking and feeling wonderful!

"I'm doing just great," Stone shared, "It's been 14 years since I had a stroke and a brain hemorrhage, but it takes such a long time to recover and it takes such a long time, once you recover, to recover your life."

It's not just about getting healthy, Stone says, but also making up for lost time and missed opportunities.

"In all the years you spend recovering, you lose your place in line in your life," Stone shared. "You get behind financially, you get behind in your career, you're not at the top of the list anymore for anything. So I think the fact that people understand -- when you have a heart attack, a stroke, cancer, whatever -- that you not only have to deal with your health and your family, but you have to start over again once you are well."

For Stone, it looks like she's found her place in line once again.

Agent X
debuts with a two-hour premiere Nov. 8 at 9 p.m. PT/ET on TNT.
