need a bf, i can recommend u one or more...
but why want to 跳楼? nothing cant be solved in this world....kill urself is definitely not a good choice
do remember, life is short...treasure everyday, every hour, every minute and every second. i m sure u would realise that there are a lot of things that u need to do.

think positively and pessimistic....life is not as hard as what u think...it can be beautiful too, depends on how u use your time, what you have done and how you think about life.
believe me, one day, u would find out the goal of your life.:)
