Quashawn Latimer was forced to choose between her chemotherapy and her rent, thanks to the government shutdown, but "perfect strangers" made sure the Navy veteran didn't have to worry about either.

"I can't negotiate with my chemo. That has to happen. If it's the chemo or the rent, chemo wins," she said then. "Worst case scenario, we lose our home."

Now, she doesn't have to worry about that either — another good Samaritan paid the family's February rent."That was amazing to me," she said. That person tracked down Latimer through a legislator from Virginia.

"It is blessings, and it is a bright side to this, and I thank God for it," Latimer told NBC Washington, which first reported her good news.

The Millersville woman still had health insurance during the shutdown, but it didn't cover all the costs associated with her cancer treatment.

"Putting cancer in your budget is unexpected," she told MSNBC — as was the 35-day government shutdown that affected Latimer and more than 800,000 federal employees and an estimated 1.2 million contract workers.

She said she was relieved when President Donald Trump announced a temporary deal ending the shutdown Friday.

"It was a very scary moment for me, having to make a choice between what I'm not going to pay to keep me healthy," she said.

While her angels reaffirmed her belief in humanity, Latimer doesn't have much faith in the government, however. She worries she can find herself caught in another shutdown come Feb. 15, when the current deal expires.

"I'm still apprehensive," she said. "I'm taking it day by day, trying to move forward."

But Latimer said what she's feeling most of all now is gratitude.

"I just want to thank all of the people that helped," she said. "I thank everybody!"
