How can i make myself feel pretty again?

Problem/Goal: My self esteem has hit rock bottom for the past 2 weeks and i feel absolutely disgusting, i hate my body, my hair, my face, everything about me—i just hate myself so much. I don't know how to feel better about myself again. I can't find the motivation to do anything. I've beent fake eating/ throwing away my food, i haven't been drinking enough water, i can't bring myself to excercise or even clean my room, I've been crying non-stop for days. Everything just feels soo overwhelming that i can't make myself do something to make everything slightly better. I don't know what to do anymore, i need help. How can i feel beautiful in my own skin again?
