The U.S. Supreme Court decision to uphold most of the Affordable Care Act led Tucsonan Gail Freyer to breath a sigh of relief.

Freyer is an insulin-dependent diabetic who had been unable to get health insurance because of her pre-existing condition.

She says she is grateful for the new legislation, which has allowed her to finally purchase health insurance through the Pre-Existing Condition Insurance Plan, although she had to go without insurance for six months in order to qualify.

"It was awful, it was frightening. It's a terrible way to live particularly in a country like this where our medical care is very costly," Freyer says.

"You feel as though you're walking on eggshells, and if you have a car accident, if you had a heart attack no matter what, no health insurance, no coverage."

She worries that without the program she could easily be denied health insurance again, so she talks with as many people as possible about why it is essential to her and millions of other people.

"I shall continue to fight for what I believe in as being very important," she says.
