Let's Write this Short Story!

Diary of a teen girl named Jane: "Dear diary,this is my first entry. My name is Jane and i live in Los Angeles,California USA. I am 15 years old,born 1999. I live with my father,my stepmother and my 8 year old half-brother Thomas,but i call him the "Tommy gun" because he is very loud. I live in a.very pretty house I was growing up without my REAL mother. She and my father got divorced shortly after my birth. My father always told me she was a prostitute and alcoholic. I was very sad when i understood this for the first time. I lived back then in an old small house. Whole my childhood was stressful. First,when i was 4-5 years old i remember my dad left me locked in the house,not once,not twice,but 3 times (or maybe even more,because i don't remember). He told me he will be back later. I was terrified staying in the house all alone. I was always afraid to go upstairs alone because i always there were black men upstairs,and sometimes i even heard stairs noise when i was alone. I was always in the other side of the room,away from the stairs. When my dad got back,i was very happy and relieved. When i was six years old,my dad made a huge step. He told me that i shouldn't grow up without a mother,and then brought me with him to a very nice house. There i met my stepmother (back then my dad's new fiancee). She took me to see her house,showed me the dolls she bought for me.I loved my stepmother and i love her now.But there is always stress in the house,about what i will talk later.The happiest part of my childhood was a year after the marriage of my father and my stepmother. We moved in her house and had lots of fun together. In the meantime my dad and my new mommy find out that she is pregnant. The whole pregnancy passed and there was no problem in the house (or with the baby). My mom and dad were in love every single day,and i was very happy too,because i got my toys,my new bike and many little dresses. When my brother Thomas was born,he was really an ugly baby for me. My troubles started again when i started going to school,and it was mostly my fault i had problems. I was very shy kid and nearly anything would make me cry in the school for the first couple of months. There i met my new friend,and now my best friend Tanya. She was my helper throughout the school time. I can still remember her words "Don't be jelly my little belly!" that cheered me up every time i was sad,even though it didn't make much sense. Many kids from my grade stayed away from me because they thought i am weird. Thanks to Tanya i have been able to get pass the problems in school,but my other problems were just starting. Tommy was only 10 months when he was taken to the hospital because of the tumor.My mom and dad were both concerned,but that drew them apart because they weren't co-operating about the Tommy's situation. Luckily the tumor was removed,Tommy has recovered and my mom and dad were back together. But this was only a start of the drama in my life. Again,with the help of my bff Tanya i started participating in the class discussions,but everytime i said something it made some other children giggle,which discouraged me. I liked arts class the most. One night, march 17th, i was getting ready for sleeping with my mom,who read me a stories before sleeping. After she left the room,i started feeling weird,like something was in my room. Then suddenly...
