Melissa Joan Hart acted as a hero to survivors escaping the Covenant School shooting in Nashville, Tennessee, on Monday.

The actress, who lives in Nashville with husband Mark Wilkerson and their three children, explained her experience in an emotional video that she posted Tuesday on Instagram.

"Hey, guys," she began the video. "For those of you that know, I live in Nashville, and what's been going on here today, um… my kids go to school right next to a school where there was a shooting today."

Hart continued, "We moved here from Connecticut where we were in a school a little ways down from Sandy Hook, so this is our second experience with a school shooting with our kids being in close proximity."

Hart assured her followers that she and her family were all fine, but said she and her husband did come into contact with some survivors as they fled the school.

"My husband and I were on our way to school for conferences," she explained, "and luckily our kids weren't in today, and we helped a class of kindergartners across a busy highway."

Beginning to tear up, she continued, "They were climbing out of the woods, trying to escape the shooter situation at their school. So we helped all these tiny little kids cross the road and get their teachers over there, we helped a mom reunite with her children…."

She appeared flustered for a moment before holding a hand up to her head and saying, "I just don't know what to say anymore. It's just, enough is enough."

Police responded within minutes of the first 911 call alerting them to an active shooter on the Christian school campus, and officers killed Hale soon after arriving.
