By making and releasing the video, the de Blasio family was able to tell the sensitive story on its own term. The highly produced video simply features Chiara de Blasio talking as gentle piano music is heard in the background. She begins the video by disclosing sheâ€™s battled depression nearly â€œher entire adolescenceâ€ and that her substance abuse flowed from that struggle. "It didn't start out as a huge thing for me but then it became a really huge thing for me," she said.
