What is the purporse for me to be living here?

This is the part where I run away from my Dad and my Boyfriend. My Dad who hates me so much and abuses me. My boyfriend who is a ****ing jerk that cheated on me and lied to me. I ran as fast as I could. I never wanted to see my Dad or my Boyfriend again. I ran as far as I can. "Don’t stop running" I said to myself. Then I started crying. I don’t know why, maybe it’s because of my Dad and my Boyfriend. I’m tired of my dad hitting me so much till I bleed and my boyfriend who kept ****ing lying to me and cheated on me and I never knew. I was so stupid, giving him so much love and all and he doesn’t even give a **** about me or what happens to me. So I shouldn’t give **** about him also. All of a sudden, I fell down and something cutted my skin kind of deep in my left leg. But I didn’t care; I just kept on running, even though it hurts so much and it starts bleeding. It was 5:45 AM. The sun was rising. It was pretty. I looked at it and remembering all the things happened in my life, remembering the fight with my dad and my boyfriend and remembering my great Family. I felt so sad and angry. So I took out my knife from my pocket. The knife was really sharp. I looked at it for a long time in my hand. I asked myself "What Is the Purpose for me to be living here if I Just Want to Die Someday?" I will keep that question in my head. I hold my knife tightly and closed my eyes. I counted to ten and I just fell down. All I saw was just black everywhere. I asked myself once more "What Is the Purpose for Me to Be Living Here, If I Just Want to Die Someday?"
Well....There is a way to find out right now....
