WATCH: Somerville High School's Winning PSA

SOMERVILLE, MA – A video created by three Somerville High School students was named this year's winner of the PSA Project, hosted by Middlesex District Attorney Marian Ryan and Middlesex Partnerships for youth, Inc. "Keep Going," produced by sophomore Alexa Sousa, junior Desi Feldman and senior Michelle Magalhaes-Teixeira, was selected for highlighting this year's theme "Challenge Yourself-Be Resilient."

The winning video premiered Thursday on “New England Cable News This Morning.” It shows students racing down a school hallway and encountering obstacles along the way. Sousa, Feldman and Magalhaes-Teixeira came up with the idea as a metaphor for the challenges many youths face today, including stress at school and home.

The goal of the 2017 PSA Project was for students to communicate a direct, positive voice to other teens. More than 45 videos were submitted from middle and high schools across the county.

"Students across Middlesex County are facing adversity and hardships every day," District Attorney Marian Ryan said in a statement. "We know that these challenges do not go away as we become adults. For this reason it is important that we teach students how to cope with these challenges in a healthy way. This PSA reflects that message well and is just one way we can communicate the importance of resiliency, in a PSA created by students to connect with their peers."

Videos from high schools in Melrose, Everett and Winchester were named PSA Project finalists. Click here to watch all the finalists’ entries.
