skinny shaming

i'm naturally skinny i can't gain pass 100 no matter what 😞 and people have the need to call me anorexic and say i throw up my food when i don't i try to gain weight and people just call skinny girls ugly and i had this girl say "how does your boyfriend enjoy having sex with you you're skinny " 😞 why do people have to say so much crap about my bodyÂ
