Watching students flee from a gunman at their school in Florida last week brought back painful memories for Austin Eubanks. Eubanks hid under a table in the school library in 1999 as two students opened fire on their classmates at Columbine High School. He survived with gunshot wounds in his hand and knees - but his greatest pain was on the inside and took years to heal. Eubanks' story is one of addiction and recovery, and the impact of emotional pain on individuals and in society following traumatic events.
