The Girls actress, whos championed body positivity in Hollywood for years, took to Instagram on Thursday to respond to online speculation about her apparent weight loss after stepping out at the opening of trainer Tracy Andersons studio.

I feel Ive induced it clearly articulated over the years that I dont give even the tiniest of shits what anyone else feels about my body, Dunham captioned a screenshot of a Refinery 29 article urging readers to stop talking about her weight. Ive gone on red carpets in couture as a size 14. Ive done sexuality scenes days after surgery, mottled with scars. Ive is cognizant of the fact that my body is an ever changing organism , not a fixed entity what goes up must come down and vice versa. I smile just as wide no matter my current size because Im proud of what this body has watched and done and represented.

In Dunhams own words, her battle with endometriosis initially led her to seek Andersons help on how to feel stronger in her own body, as she struggles with chronic and often debilitating pain. Last year, the 30 -year-old canceled press appearances ahead of the Girls season premiere to remainder after a particularly rough patch with the illness. According to Dunham, exercise has alleviated some pain and allowed her to control the endometriosis and anxiety.

After her appearance at the fitness event, troubling reports described Dunham looking happy and healthy next to side-by-side photos of the actress. A Daily Mail headlineeven extol Dunham to be half the girl she used to be.

My weight loss isnt a triumph and it also isnt some sign Ive finally given in to the voices of trolls. Because my body belongs to ME at every phase, in every iteration, and whatever Im doing with it, Im not handing in my feminist card to anyone, she continued. I refuse to celebrate these bullshit before-and-after pictures. Dont we have infinitely more pressing news to attend to?

Thank you for this @Refinery29. I feel I’ve stimulated it pretty clear over the years that I don’t give even the tiniest of shits what anyone else feels about my body. I’ve gone on red carpets in couture as a sizing 14. I’ve done sex scenes days after surgery, mottled with scars. I’ve is cognizant of the fact that my body is an ever changing organism , not a fixed entity- what goes up must come down and vice versa. I smile just as broad no matter my current size because I’m proud of what this body has seen and done and represented. Chronic illness sufferer. Body-shaming vigilante. Sexual assault survivor. Raging hottie. Just like all of YOU. Right now I’m struggling to control my endometriosis through a healthy diet and exercising. So my weight loss isn’t a triumph and it also isn’t some sign I’ve finally given in to the voices of trolls. Because my body belongs to ME–at every phase, in every iteration, and whatever I’m doing with it, I’m not handing in my feminist card to anyone. So thank you to my girl @ashleygraham for writing so gorgeously about this on @lennyletter( connection in bio ). Thank you to @ tracyandersonmethod for teaching me that exercise has the power to counteract my pain and anxiety, and to @jennikonner for being my partner in FUCK IT. I refuse to celebrate these bullshit before-and-after images. Don’t we have infinitely more pressing news to attend to? So much love to all my web friends who demand that life be more than a daily weigh in, who know their merit has nothing to do with different sizes, who fight to be seen and hear and accepted. I love you- Lena
