Arrgh I hate her

okay so this is what happened

she slammed a skateboard into my shin on accident, but like she kinda meant to and i cant even walk without excruciating pain. Shes never even said sorry for any of it. She even called me a ***** for complaining that I couldn't walk and I wanted her to sit down with me because I couldnt walk since my leg was completely limp ( like dead I couldnt move it) and I didnt want to be alone.

and now just had a breakdown cause ive been friends with her since kindergarten and shes talking trash about me. I know I should ditch her and i have it's just trapped in my brain though you know? I've been getting dirty looks and crap when i'm the person with the aircast on because she's telling lies !!! I had like a mental breakdown about it today. Any Help???
