insecurity and self-esteem

ever since i was little i’ve always been told that i’m really pretty and you would think i would be pretty confident in myself because almost everyone tells me that im not ugly. idk why but ive always felt so ugly and disgusting and i can’t even get my picture taken. all i do is look at myself and pick out everything i hate. and it keeps getting worse and worse and i don’t even wanna look at people anymore so they don’t have to see my face. i don’t wear revealing clothes either. but i’m just sick of comparing myself to everyone and all i want is to be pretty.
