Should i report this to a doctor as child abuse?

My mom was yelling at about how big of a failure i was after she caught me smoking pot. I was laying in bed crying and my mom was yelling at me to get up and do something with my life (im severly depressed and have been since 6th grade.) a few days prior to the yelling i was in a bike accident where i sprained my wirst and badly bruised my shoulder. in rage my mom grabbed my recovering wrist and attempted to pull me out of bed but instead she just twisted my wrist and injured my shoulder even more. I dont think she caused any serious problems but my shoulder and wrist were almost better before the incident and now they are worse. Should i go to a doctor and tell him/her what happened or should i wait till i meet with my regular doctor about depression. This is going to be the first time ever talking to my doctor about depression. im 16. I already have a apointment scheduled with my regular doctor but i dont know when it it. What should i do?
