Don't let it be normal for people to hurt you, don't let them control you nor do you let them beat you or harm you in any way.. but I can't say this without sounding like a bigot.
Like me I was abused by my friends, with them kicking me in my face and leaving me outside in the cold for hours (I usually just left to go home) Don't let people tell you "No one would ever love or marry somebody as ugly as you." or even a famous one among my bully, "Ew, how could you be so fat?"
Immature, and don't call anybody ugly because they don't meet up to your standards.
Don't let people tell you what to do, don't let people whip you with wires because they say your ankle is "fine".
(personal bleh)
and so much more, just don't these are from personal experiences I could go on, which I want to but I told my mom and I laughed at myself because I USED to think this was all normal.. I remember getting pulled by my hair and spat on by my "friends" I suffered bulimia because somebody never let me just live my life and called me "fat."
Talk to somebody, it helps so much rather it be somebody on the internet or your mom.
Talking helps and you ignoring them because they want to talk makes them feel as if it will just burden others.
