My Grandfather is an a**hole (rant)

Please here me out. My grandfather is a natural born douche bag. He talks bad about me, my mom, and my grandma to his folks back down south, and my grandpa told my mom. So one time, I was fixing sausages, I wanted a nibble pf pancakes in case the sausages got done late, then I won't eat that much, as I try not to eat anything heavy after, 7:00pm. So the douche bag granddad had the flipping audacity to call me fat, and I don't even eat that much, because if I eat too much, I get sick. You best believe it upset me, it drove me to want to look like a YouTuber, Eugenia Coony, in case you don't know, she is an anorexic YouTuber, and some parents want her channel banned because they think she is a bad influence on their sons/daughters. Onision, a Youtuber everyone hates, he said in one of his videos that someone wanted to look like Eugenia. You know that's bad. I was triggered to go back to my old eating disorder, that I once had in 2012, I was like screw it, I don't mind going back to the ER, anything so I won't hear my own flesh and blood shame my weight. I am far from obese, so in his mind
not thin as a pencil=fat.
he even talks about my weight to his mom, and she doesn't even care. My mom heard him talking about my weight to my grandma and she told him off. We called me aunt and talked to her. He calls my grandma stupid, I heard it with my own ears one time, he yells at her, tells her she doesn't know anything. If I were her, I'd divorce him. No man would EVER make someone hate their body, or insults a lady. I can't call him a man, its a disgrace. He thinks we're idiots. But we are not stupid.
I live in a hell hole I call a "home" there is no way out, no money to move, so I am force to go mentally insane. When I do make enough money to live on my own, I am never coming back to the hell house, ever.
