Ok at my school my friends little sister -I swear she is possessed- is not right in the head as in she is crazy, I will be going about to my business at recces and she will come up to me and start randomly kicking and punching me and will chase me until I get away. She is scaring me and is making me go into emo mode- my friends nickname for when I get pissed or angry- what can I do about her and the attacks? Thanks for any answers
