The former Rhode Island Congressman, 52, opened up toNBC Nightly Newson Friday, where he emphasized the need for more attention on mental health after his cousin, whospoke candidly about her battle with depression, died from anapparent overdose.

Patrick, who is the son of Ted Kennedy, also praised Saoirse, 22, as a “hero” for being open about her struggles, continuing to push the conversation forward, and getting professional help when she needed it.

“And we mourn her loss but her memory will live on as someone who wasn’t going to keep silent and wasn’t going to be feeling as if she had something shameful, but rather something medical that she sought treatment for,” he continued.

“This affects every single family in America,” Patrick added. “It’s way past time that we deal with this in a way that we would deal with any other public health crisis.”

In his tweets, Patrick encouraged his followers to read Saoirse’s words before urging for the nationwide stigma around mental health to end.

“Saoirse’s sincere account of her depression is a powerful reminder of how so many people suffer alone and feel isolated,” he wrote alongside the link to the published piece. “I am proud Saoirse was able to be open and tell her story. I encourage everyone to read her words.”

“Feel what she felt. Do whatever you can from your position in life to stop the isolation, the stigma, and the devastating lack of acknowledgment that often leads to tragedy,”he continued.

“Families across the nation, including ours, are suffering,” Patrick finished. “We must come out of the shadows.”

A source close to the Kennedy family told PEOPLE that Saoirse was found at her grandmotherEthel Kennedy‘s home Thursday after an apparent overdose.
