After two years of rigorous battle against breast cancer, Shannen Doherty is back to what she loves the most — acting. In an emotional post, she summed up her struggle not only with the deadly disease but how it prompts people to think the person is 'weak to be hired' at the workplace.

"Was back on set today. It's been a rough two years fighting cancer. As an actor, people bench you. They assume you're too weak, not able etc. and yet it's something like work that invigorates and renews strength to conquer the unimaginable beast," she wrote on an image that she shared on Instagram.

The 45-year-old American actress was diagnosed with cancer in 2015 and has been through painstaking treatments to beat the disease. In her moving post, the former Charmed actress compared herself with a vintage car as she prepares to warm up and restart her paused acting career with new zeal.

"I compared myself to a car today. That vintage Shelby that's been in the garage too long. It's still a great car. The best. Just needs time for the engine to warm up and it's good to go. Performing like it's supposed to. I'm grateful for today. Grateful for every day," she added. With her latest post, Doherty teased her upcoming show Heathers under Paramount network which is scheduled for 2018 and thanked the crew for the same. "Thank you @heathers for letting me play and be someone else today. Great crew, great writers, great cast, great show, great director."

Fans are in awe of the Beverly Hills 90210 actress for her inspirational journey and never say die attitude. "You are an amazing and inspirational woman," one fan commented on the image sharing site. "Back and better than ever, I'm sure. I've always admired your work, but now I admire your strength and perseverance. Wishing you nothing but the best," added another. "Your hardest times often lead to the greatest moments of your life. Keep going. Tough situations build strong people in the end."
