Shannen Doherty really is warrior and we are so proud of her bravery throughout her cancer journey!

The former Beverly Hills, 90210 actress has been fighting cancer since March of 2015. Although the process is hard and tough on her, Doherty has been sharing every step of her battle with her fans on social media, which makes us love her even more.

On Friday, Doherty shared a flashback photo from one of her chemo treatment days and revealed that it is definitely hard to stay optimistic all the time while fighting cancer.

Although it isn’t always easy, the 45-year-old star also pointed out that she has hope and faith and that’s what helps her get through it all.

Wow, if this isn’t inspiration to overcome all the problems we have in our daily lives, then we don’t know what is!

Doherty has been strong throughout her battle thanks to her family, friends and fans’ support. In fact, fellow actress Sarah Michelle Gellar’s constant shout-outs manage to make us feel more empowered and hopeful about Doherty and her cancer fight with every post.

Another recent post shows Gellar’s continued commitment to her friend.

“Today is recognized as #internationalbreastcancerday, although for some people, that is everyday. I am only a footnote in this picture. To my left is the @theshando, my friend who is kicking cancer in the you know what. But more than that, she is sharing her battle, so people fighting this horrible disease know they are not alone,” Gellar wrote alongside a sweet photo on Thursday in honor of International Breast Cancer Day.

“I am honored to know you both. Breast cancer is nowadays the most frequent malignant tumor in the world. But with early detection and incredible doctors like Dr Piro, breast cancer can be fought and won,” she said.

Although Doherty’s cancer diagnosis is difficult news, her optimism is something to be admired, as is Gellar’s continued support for her longtime friend. You go, ladies!
