'Bridgerton' star Ruby Barker says she's 'so happy to be alive' in honest video

She recently told her fans that she was hospitalized due to her mental health.

Ruby Barker, who plays Marina Thompson in the hit period drama "Bridgerton," has shared a new update on her health, following recent treatment in a hospital for unspecified "mental health struggles."

Barker took to Instagram in a video recorded while she was soaking in a hot tub to update her followers, thanking her family, friends and doctors for their support.

The actress, who shared a vulnerable video last week revealing she was in a hospital due to her mental health struggles, said in a new update Monday that she has been discharged from the hospital and is in a better headspace.

"You've made me feel so happy to be alive," she said to those who offered her support, "and I'm so grateful for that."

On this support, she commented, "it really made me feel less alone," and hoped "shining a light" on her own troubles can help others.

"I can't wait for the future," she shared. "I'm doing ok for myself. I'm sat in a beautiful environment right now, just taking a bit of time to myself to relax and breathe."

"Getting outdoors, going for walks, speaking to loved ones, trying not to ostracize yourself, that's a really big step," she continued.

The actress then shared advice she would give to her younger self: "I would just tell myself, listen, it's not all doom and gloom, even when you hit rock bottom."

She also revealed words her "Bridgerton" co-star Claudia Jessie previously told her that impacted her. "She told me to flip the coin...'It might be dull on one side, but just flip the coin, and you'll find it's shiny on the other.'"

"Find the funny, find the light," she continued. "Anybody that's in a dark place right now, I just want you to know, I see you. I feel you. But find the funny and flip that coin."
