The Long Island EMT shot by a crazed, assault-rifle-toting gunman yesterday described the terror of Tuesday night’s attack.

“It was scary, I just wanted to make sure I could get cover and get out of there,” said volunteer medic Justin Angell, 20, as he left Nassau University Medical Center. “Once I felt the pain, I just started running as fast as I could.”

Angell was blasted in the torso by Jason Beller, who opened fire on rescue workers after crashed his pickup in Bellmore. Beller, 31, eventually was shot dead by cops.
