Im 13 years old and I have something very wrong with me. When i look in the mirror i think i am beautiful and i think i look better than everyone else. No one tells me im pretty except my family so i have no reason to think this. I know im ugly but its like ive convinced myself that i am pretty and i can’t get it out of my head. I cut myself to try and punish myself for feeling like this but its not working. Am i insane? Help me.
