A United Airlines flight attendant who previously shared her story as a transgender woman in a video for the company has died after posting an emotional note to her social media channels.

In posts to herInstagramandFacebookpage on Monday morning, Kayleigh Scott of Denver penned a heartbreaking letter to her friends and family that asked them to remember the “good memories we have shared.”

“As I take my final breaths and exit this living earth, I would like to apologize to everyone I let down,” Scott wrote. “I am so sorry I could not be better. To those that I love, I am sorry I could not be stronger. To those that gave me their everything, I am sorry my effort was not reciprocated.”

She continued: “Please understand that me leaving is not a reflection on you, but the result of my own inability to turn myself for the better.”

After naming a few of her loved ones, Scott apologized and said, “I will see you all again on the other side.”

Later that day, Scott’s mother, Andrea Sylvestro, confirmed her daughter died after posting the letter.

PEOPLE contacted the Denver Office of the Medical Examiner and the Denver Police Department for more information.

In 2020, Scott starred in avideofor United where she opened up about transitioning and how she felt her peers at the company supported her.

“This is a story that I know is so important for me to continue sharing,” she said in the video. “Not for me, but for those out there who are still fighting social norms, the boundaries set upon them, [and] fighting themselves.”

Scott previously spoke out about when she realized she was transgender in an interview withSomething’s Coming Up.

“Growing up, living as a boy early on in my life, I started to figure out things were different… these clothes don’t feel right, these toys don’t feel right,” she recalled. “I was about 9 when I started to realize that… I don’t think I’m a boy.”

But in her teens, Scott said bullying affected her mental health to the point where she considered taking her own life.

“The bullying, hiding who I was, not addressing it, it all built up,” she said, “and it got to a point where I couldn’t hold on any longer.”

In 2021, Scottwrote on Facebookabout her progress since publicly coming out as transgender.

“Two years ago I came out and made my transition public,” she wrote. “It’s remarkable to reflect on the past two years and see how much I’ve grown emotionally, physically and spiritually! Despite the challenges I have faced along the way, I have managed to stand taller and continue fighting for myself and everyone out there who does not have the privilege to use their own voice. Here’s to being unapologetically me. #BeCounted”
