Dove Cameron, Sofia Carson, Kenny Ortega and more arepaying tributeto their late friend andDescendantsactorCameron Boyce.

The"Boyfriend" singeropened up about Boyce’s lasting impact on her life atThe Cameron Boyce Foundation’s Inaugural Cam for a Cause Gala on Wednesday.

Boyce died at 20 in July 2019 aftersuffering a seizurein his sleep due to epilepsy.

“I think that Cam was the most alive person I’ve ever known,” Cameron told PEOPLE exclusively. “I think that in that, he has inspired me to be more alive, he has inspired me to be more human, more deeply feeling.”

“And I think that’s one of his legacies, he touched people in that way,” she continued. “In a way that I don’t know anybody else has. And also of course, wielding peace for all of the world.”

The Disney Channel star called the loss of Boyce “eternal” and added “the pain is lifelong.”

“It just changes and shifts position in your nervous system, but I don’t think it ever goes away,” she explained of her grief. “I don’t think you find peace, but I do think grief finds a way to transform you for the better, make more space in you to hold more of it.

“You become bigger,” she added. “It’s not that the grief becomes smaller, you just become bigger to accommodate.”

Cameron also said it was “highly emotional” to attend the event, which was organized in support of the Cameron Boyce Foundation’s mission of curing epilepsy through funding research, education and awareness.

“I think that we all were so intimately close with Cam and a lot of us haven’t been all together since his celebration of life,” she shared. “So it’s definitely a lot of mixed emotions but I know a lot of us are very excited about carrying on the work he wanted to do and couldn’t finish so we’re very excited about that.”

Carson, who performed at the event, also called the evening “surreal and emotional.”

“Our hearts are forever yours,” Carson wrote in the moving caption.

Cameron’s sister Maya attended the event with close friends and said “the familiar faces have been very comforting” after losing her brother.

“Of course I’m feeling sad, but I’m also happy for my parents,” said Maya. “This has meant so much to them. My mom started the foundation a little less than three years ago, and this is exactly [Cameron’s] style — outdoors, intimate, with everyone he knows. It feels exactly like Cameron.”

Other loved ones in attendance included Boyce’s formerDescendantscostars Sarah Jefferey and Maz Jobrani.

“I think of him daily. I play the music that he showed me,” Jefferey told PEOPLE of how she keeps Boyce’s memory alive. “Keeping in touch with the people who also knew him is huge. We’re all rallying and supporting each other, and I know he feels the love.”
