It all started when I was two years old. My parents didn’t get along and got divorced（离婚）. I hated that I couldn’t see both of my parents at the same time. So my dad, my younger sister, Alexis, and I went to live with my grandma and grandpa. We lived with them for almost six years. My mom, on the other hand, lived with her boyfriend Michael in Oklahoma. My life was really good, but when my mom called to check up on my sister and me, I cried myself to sleep. I missed her so much.

My life at my grandparents’ house was really nice. And then on Friday, May 15, 2002, my grandpa died of cancer. I cried for seven days straight. My dad and his new wife were worried about me. So they took me to the doctor and they said that I was too sad and that I needed to find something happy and healthy to do during the day.

I prayed（祈祷）to God every night saying that I was sorry for getting myself sick and I also prayed for him to take care of my grandpa. I still pray to this day. And now, at my mom’s house, she has a four-year-old girl, my half-sister, Macie. And I have my step-dad（继父）, Michael, there for me. I really like Michael. He’s really good to me and my sister. And at my dad’s house, I have two little brothers, Blake and Justin. Blake is two years old and Justin is ten months old. I have so much to be thankful for, but I’m still looking for more.
