Disabilities Advocate Posts Inspiring Beach Bikini Pic

"It's not about what you have."

A 28-year-old Georgia woman who lost all of her limbs shared a bikini photo and an uplifting message to Facebook on Monday.

Aimee Copeland contracted necrotizing fasciitis, a rare flesh-eating bacterial skin infection, after a zip-lining accident in 2012. In order to save her, doctors amputated her two hands, her left leg and her right leg below the knee.

In the weeks following the accident, Copeland vowed that she would continue to live as if the accident never occurred.

"I wasn't going to let anything hold me back," she told People. "There is always hope for another day."

After completing rehab, Copeland received her second master's degree in social work. She is now an advocate for people with disabilities and she has plans to open a nonprofit holistic community center.

"My self-confidence has never been higher," she told People. "I've let go of the girl I was before. I've completely embraced who I am."

Four years after her accident, Copeland snapped a photo of her on the beach in San Juan, Puerto Rico. The photo went viral on Facebook as users praised her for being courageous and inspiring.

"It has taken me a long time to become comfortable with and accept my new body," she wrote on Facebook. "We are ALL made with imperfections and there is so much beauty in our flaws. The scars and skin grafting build character! It's not about what you have -- what you do with what you have is what really counts."
