In June, Roberts announced she had myelodysplastic syndrome. Back in 2007 she battled breast cancer. Through it all she has remains resilient.

"It's as much about the mind as it the body. Thoughts are so powerful. You've gotta change the way you think. In order to change the way you feel. And let me just say this last thing. I feel the love. And I thank you for it. Thank you," Roberts said in a video on ABC's Good Morning America.

Her older sister Sally-Ann Roberts was a perfect match and donated her bone marrow to Roberts.

Roberts and Sally-Ann grew up in Pass Christian along with two other siblings. Their mother, Lucimarian Roberts passed away in August.
