Cindy Roush, one of Mullins' former co-workers at the Teays Valley Center, told the court she didn't hate Mullins but her actions hurt "more than anything."
"I don't feel safe," Roush said, her voice breaking. "I go to work and think about it. I just feel scared all of the time."
Becky Hill, who manages the bank, said Mullins' actions changed her life.
"I like her," Hill said. "I don't hate her for what she did. But it's changed my life - not for a day or a month, but a complete change.
"I was never afraid of work, but now I am. I was never afraid of my home, but now I am."
Mullins apologized for her actions. A slight woman, she stood wearing a prison orange jumpsuit and spoke softly.
"I am sorry," she said to her victims, who sat together on the right side of the courtroom. "It's not the person that I am. I was under the influence of something I shouldn't have been under.
"I'm not going to make excuses."
Mullins has a documented drug addiction. She told the court she had been addicted to oxycodone for the last three and half years. She tested positive for oxycodone and morphine before her federal arraignment in May.
U.S. Attorney Booth Goodwin said the robberies were shocking.
"This case shows in very stark terms the devastating effects of the prescription drug epidemic," Goodwin said. "The defendant's crimes were shocking, and now she has 10 years to think about the effects of those crimes.
"As the court noted, the significance of this sentencing should also serve as a deterrent. The right path is not toward crime but toward treatment."
Mullins requested to be placed at a prison close to home. Johnston said that would likely be Alderson Federal Prison Camp, a women's minimum-security prison in Monroe and Summers counties.
She also has been ordered to pay restitution to the bank and the nursing home.
