鈥淭en years and two months ago, I survived the Sandy Hook shooting,鈥� Matthews says. 鈥淲hen I was crouched in the corner in school in Newtown, Connecticut, on 12/14/12, I was hunched in the corner with my classmates for so long that I actually got a PTSD fracture in my L4 and L5 in my right lower back. I now have a full-blown PTSD fracture that flares up anytime I have a stressful situation.鈥�

鈥淭he fact that this is a second mass shooting that I have now lived through is incomprehensible. My heart goes out to all the families and the friends of the victims of Michigan State shooting. But we can no longer just provide love and prayers 鈥� [there] needs to be legislation, needs to be action. 

鈥淚t’s not OK. We can no longer allow this to happen. We can no longer be complacent.”

Monday night鈥檚 shooting took the lives of at least three students, with five others still critically wounded Tuesday. 

Matthews鈥檚 video quickly went viral Tuesday morning; a tweet from Shannon Watts, founder of Moms Demand Action, had already seen 42,000 likes and nearly 14,000 retweets by 1 p.m. 

The Michigan State shooting occurred mere hours before the fifth anniversary of the Valentine鈥檚 Day school shooting in Parkland, Florida, which resulted in 17 deaths. Some of our previous coverage of the fallout from Parkland:
