how do you guys cope??

im feeling so down and sad. i hate that my life is on pause and i suffer from social anxiety everytime i go out. whenever i do my makeup in dark or dim lighting and step out in natural sun, i look absolutely hideous. my lower face is so wide and my chin is square, my heads like a watermelon. ive been trying to stay off tiktok because i keep comparing myself to even average looking girls and im tired of it. i have slightly downturned eyes with a round bulbous tip and from the sides my nostrils extend a lot. idk how to be confident when i look and feel like this. i feel trapped and stuck like i just wanna live my life and be happy but i cant. i try to take photos of myself and feel even worse because my nose stands out so much. what should i do? im so tired of isolating myself and not seeing people or having meaningful relationships sigh
