thanks to everyone
Thank you to everyone! to Paul, all my classmates, my friends in china and EU, especially my mom.
cintinuously being depressed and upset are useless for me, and I should move on living happily for people who care me.
I will concentrate on my study from now on, and after graduate I will go back China to live with my mom. during these years I ignored her too much, it's time to be a good daughter.
thanks to everyone again.
