I am the girl whose always in constant pain, but looks completely healthy. I am the girl who always calls in sick. I am the girl who has a pharmacy in her backpack. I am the girl whose always going to doctors appointments. I am the girl whose always tired. I am the girl with the invisible disease you can't pronounce and don't understand. I am not "lazy". I am not a "whiner". I do not make up the "pain in my head". I have Endometriosis. Yess, I am THAT girl with endo..
