My GF abuses me..

My girlfriend physically abuses me and I dont know what to do.. I feel a lot of pain and feel that rejected badly. We've been together for 4 yrs and she's had anger issues and everytime I do / tell something she gets angry. last sat she kicked me so hard that I couldnt take it. I dont know what to do. pls help

get her into an anger class and and ask her why she has to be so pyshical next time she does somthing restrain her and call the cops
