How do I write my life story?

I'm 18 years old, single, but I feel like a broken lover when I listen to songs. I'm a bit boring and a duffer too. People say I get angry over small things. It's just me, my mom, dad, and brother in the family. I love listening to music and I read books too, but not comic books. I like making friends, but I'm an introvert. I really like chole puri and dahi vada. I'm not very emotional; I'm strong, but sometimes I do get a little emotional in certain situations. I always have complaints with God. My mom is strict because she is my math teacher, and I used to fail in that subject. My dad is my best friend; I share everything with him. I have a rivalry with my brother; we fight all the time. I wasn't thinking of anything else right now, so I'm just writing this.
