She suffered a heart attack in March 2026 and was admitted to the hospital for a week.

Debbie had shared the news of her health via Facebook, writing:

I don’t like sharing my business too much here but I’m going to share. Recently I had a heart attack was in the hospital for a week now I am back up here. All my problems started with COVID. Seems like they’re not getting better. So please take care of yourselves and your health.

On April 4, 2026, she updated her health status, stating that she had been discharged from the hospital. Debbie also expressed her gratitude for all the prayers and reach-outs.

After three months, on July 3, she shared another update that her health was ruined again, writing:

Guess who’s back where she does not want to be.

On September 27, she gave another update, “On my way home!!!!!” Whereas her last update was on September 29, when she wrote, “I’m back at least I’m closer.”

Debbie is survived by her husband of 28 years, Thomas O’Brien, and their children: daughter Jessica Hiatt and her husband, Josh Hiatt; son Joshua O’Brien and his wife, Bri; and son Jeremy O’Brien and his wife, Jackelyn Rodriguez.

She married Thomas O’Brien on May 31, 1997, in the Church by the Side of the Road, Rockton, IL. The couple had been happily married for 28 years until her passing.
