being ugly will be the death of me

i’m well below average. i never leave the house and when i do im practically invisible, im never greeted at stores or helped, no one looks at me, people don’t hold the door for me, cashiers are short and avoid looking at me. im so ugly people are almost mad at me for it. all i do is sit in my room all day and self harm. i’m building the courage to just do it but im scared. i used to have hope for my future but im just ugly and nothing will change.
