On the Bright Side, I'm now the Girlfriend of a Sex God

My novel " On the Bright Side, I'm now the Girlfriend of a Sex God" is about a 14- year old girl that fell in love with a 17-year old "Sex God". The boy has a problem with the big difference of age and dumbs the girl, that is now terribly unhappy. The book is written in a diary form and shows the girls life. The problems in her family, the life with her friends and all the unavailing tries to get the love of her life back. Her life is very stereotypical for her age. She feels like nobody likes her and her whole life is a tragedy.
I really liked this book, because it was relaxing to read and it reminded me on my situation when I was in her age. It happend exactly the same thing as in the book, and I felt misunderstood. Everything was meaningless and I just felt like my life was ruined. I could never imagine to feel better some day. But now I know that it is just the way that you feel for a while and then you get over it and go on with your life. I thought the book was very funny, because even if the girl was in a bad mood, she could still be sarcastic and laugh about herself.
She made everything worse than it actually was. She felt like nobody cared about her and everybody was just interested in their own lifes, but it was actually her that was just thinking of her own good.
I liked the perspective that the story was told from. The diary form showed all the girl's feelings and I felt like I am the person that is experiencing everything. The girl is a round character.
It was also funny to see how often she actually wrote in the diary and how her thoughts were floating in her head ( " 2:05 a.m. ...." and "2:05 and 30 secs...." ).
She changed her opinion on things very quickly sometimes and you can see all these thoughts in a funny way all the way through the story ( "1:06 a.m. - Oh I love him, I love him." "1:10 a.m. - I hate him,....").
