"It's a living nightmare for me right now, because I can't get the sounds out of my head. I can't get the pictures out of my head," Garcia said.
Chris Enzo, a friend of a shooting victim, said his friends feel too scared to step foot outside their homes. Still, he had a message of strength in the face of terror.
"We want Orlando city to stay strong and that we want everyone to realize that we don't want to cower down due to terrorist attacks and we don't want to give into fear," Enzo said.
The gunman, identified by authorities as Omar Mateen, 29, opened fire inside the packed Pulse club early Sunday morning.
