After doctors saved her life, this 12-year-old girl is committed to paying it forward

Lalia Susini's terrifying accident on a porch swing has pushed her into the ultimate quest, a mission of goodwill for other injured and sick children.

The 12-year-old Los Angeles girl had been pursuing a career in acting and fashion, but now has her mind set on becoming a doctor, the result of a harrowing accident that led to several brain surgeries.

"I thought I was going to die," Susini, who most recently starred in ABC's "Station 19," told CNN. "I just had no idea what happened."
