Writing an emotional open-letter online, she admits she wants privacy over the matter, but is ready to share some vital information.
"I haven't had the greatest year. Maybe one day I'll talk about it, but for now, I'd like my privacy," she began, on Twitter.
"I will say that this year has brought a lot of changes and with that, physical changes. I have been told that I can't work out, which, for me, is very upsetting. I am an activist for activity (and for eating junk food in bed, but it's all about balance right?) I love to be outdoors. I love to be STRONG (I'll be using that word a lot.) Strength is everything. Being strong has gotten me where I am, both mentally and physically.
"I am not a fan of 'being skinny,' which many of you have told me that I am too much of. 'Eat a burger.' 'Your head is bigger than your body and that's disgusting.' And you're right! No one's head should be bigger than their body, but considering I've basically been on bed rest for the past few months, I've lost a lot of muscle mass. My circumstances have put me in a place where I'm not in control of what my body looks like, so I strive to be as healthy as possible, as everyone should."
"Oh and no that's not photoshop. Those are my legs. Those are my arms. I write this because I've been accused of promoting anorexia in, ironically enough, an anti bullying post. And I want young girls to know that that's NOT my intention. I posted a picture of my boyfriend's apparel line, in which part of the proceeds go to the anti-bullying alliance, and in return am bullied.
"Which made me laugh but then it dawned on me that young girls are reading that I'm promoting anorexia due to my weight. While these comments don't affect me, they may affect others."
The post goes on, explaining that she isn't happy with how she looks right now and it isn't fun for her to see her hard work at the gym fade away, but she is strong and won't give up.
Sarah shouldn't have had to feel pressured to let the world know that she is going through something medically right now, but it's a good reminder to everyone that we will never know what is happening to somebody behind closed doors.
"I know that my face is swollen from the medication that is saving my life," she explained. "For those on Prednisone, I know what you're going through and I commend you sticking it out as I have."
ALL the love and well wishes sent her way <3.
