I didn't mean to kill her ENG writing

I didn't mean to kill her. I was in a bad mood and she kept talking and talking till I got angry. I pushed her really hard and she fell. After I pushed her I left, and go somewhere quiet and I can be my self. I spent my whole night on the edge of the mountain. when I was walking home I wonder why are there so many people outside our house and police were searching inside. I freaked out so I ran quickly to our house, and when I arrived I was shocked she was dead. the police talk to me but I couldn't speak because I was stunned by what happens to her. they gave me some time to rest. and after an hour they came back to me and ask me what happened to her, I said that we had a fight last night and I was so angry that I accidentally pushed her. I didn't know that she bumped her head because after I pushed her I quickly left. I deserved to go to jail to what I did to her, so take me.
