Eyelash Answers

well both of my sisters have a lot of spanish features like big dark eyes, eyelashes, dark eyebrows, olive skin, shiny black hair. they are also short, thick & curvy.
me on the other hand im the complete opposite. im taller then them & underweight/lanky, i dont have any curves or boobs. im white, my skin is more pale than olive, & i have lighter hair, lighter eyebrows, small eyes, & basically very little eyelashes. makeup does not help me because i still feel ugly compared to them. i also wish my eyes were dark brown but they are light brown & this makes them look smaller.
every time i see them i get really upset, i dont know why. i just wish i could look like them. i cant accept that im so ugly & they are so beautiful. its like when i start to feel in a good mood my appearance brings me down. i can never just be happy. any advice?
