I hate this

I really love my mother but why is she like this? I've always tried my best but it's always not enough I always get blamed for the dumbest things that I didn't even do she always lets her anger out on me she will tell me how ugly am I lets not forget how she abused me at the age of 4-8 because I was outside and I got myself a bruised knee, she always makes everything my fault when it clearly isn't when I try to stand up for myself she will yell at me and say that I'm being disrespectful one day I will leave this household
