Selma Blair penned an emotional note to her younger self, and fair warning, you may well up with tears reading it.

The open letter was published in a special edition of People and featured commentary as well as photos of stars like Eva Longoria, Rosario Dawson and Christina Ricci, among many others.

In her piece, the Cruel Intentions alum took a minute to reflect on her career and aspirations before sharing a message of hope.

She wrote:

"I know you are scared of growing up. You think you won't know how to do anything successful adults do, but it will be okay. Don't worry your mind about the future so much."

"I remember you at this age so well and how this picture right here was taken while REO Speedwagon was playing, and you felt something."

"That thing you couldn't put your finger on. It's hope. Trade your fear for hope. Keep reading. Write every day. Please trust yourself. Tell the truth. Observe. Good things will happen. And horrible things. And it will all be part of finding your footing and carrying on. You are worth loving."

The 50-year-old actress concluded with a few last words of encouragement, adding, "P.S. You bought yourself the horse you always will hope for. His name is Mr. Nibbles. You will be able to do plenty. Please don't worry. And breathe in deeply. And exhale. Keep passing the open windows."

The Hellboy star's letter comes about a week after she inspired fans with another candid interview, this time talking about using her cane–a tool she's used for support following her 2018 diagnosis with multiple sclerosis (MS)–in the public eye and how she has helped younger people feel more confident using their canes.

"I have an emotional and physical attachment to the cane," Blair told British Vogue in her latest cover story for the outlet. "I settle in my voice and body as soon as I hold [it]. It’s an extension of me. And I know it adds to visibility. So many younger people have started publicly embracing their sticks more. I do think representation matters. If I can help remove stigma or over-curiosity in a crowd for someone else, then that’s great."

Since being diagnosed with MS nearly five years ago, the actress has become a strong advocate for the disabled community, determined to motivate others and use her platform for the greater good. She previously opened up about her decision to appear on season 31 of Dancing with the Stars, saying, "[It's] such a gift to inspire anybody."
