'He wasn't going to stop killing' says Pulse survivor Patience Carter

Patience Carter, a woman who was shot during the attack at Orlando's Pulse nightclub, spoke out Tuesday from a hospital bed at Florida Hospital.

Before going into detail, the 20-year-old first read a poem she wrote while in the hospital.

Because I could feel nothing

Looking at the killer's machine gun throughout my right peripheral.

Looking at the blood and debris covered on everyone's faces.

Looking at the gunman's feet under the stall as he paces.

The guilt of feeling lucky to be alive is heavy, it's like the weight of the oceans walls crushing uncontrolled by levies. It's like being drug through the grass with a shattered leg and thrown in the back of a Chevy.

Being rushed to the hospital and told you're going to make it, when you laid beside individuals whose lives were brutally taken.

The guilt of being alive is heavy."

Carter explained that she was visiting Orlando with friends and this is her first time in Florida. The group researched local nightclubs and establishments before deciding to go to Pulse.

She then detailed the terrifying moments when she realized what was happening.

"We started hearing the gunshots going off in the middle section," Carter said.

Carter said she ended up in a bathroom at the nightclub with several others and the gunman, 29-year-old Omar Mateen. She described hearing Mateen make a 911 call and pledge allegiance to ISIS.

He said "he wants America to stop bombing his country," Carter said. "We knew what his motive was and he wasn't going to stop killing people until he was killed."

Authorities said Mateen fatally shot 49 people in the massacre. More than 50 people were injured. Mateen was shot and killed by police officers.
