My mom has been abusing me since I was six and I'm now 13 should I tell the guidance counselor at school? And get away? It all started when I was six and I accidentally used all her ink in her printer and she beat me and made me stay up all night And color then in. There was also a time when I was 7 she thought I lost my birth certificate and she beat me and made me look through the garbage cans and she ended up finding it in her purse and there were many other times she has beaten me and I can home 5 minutes late from school and she beat me tried to throw me out the window threw scissors at my head and metal bowl banged my head on the wall kicked me in my back. And then the other day she really beat me I have bruises I can barely move, she hit me with a chair punched me in my ribs and I couldn't breathe and kicked me in my back while I was on the floor and I'm just scared to be here sometimes I feel like taking a blade to my throat
