Changed life

well i think my life changed a lot for about 10 month.
I felt in love with a guy who seems to hate me, i lost my best friend ( my dog), i had to chance my school ( i graduated and had to go to another one)
Well and what changed most is myself. My clothes, my character, my feelings.

Since i knew GC i was a girl with more selfconfidence than before. But know everything is away. I dont know why... i changed....
