Comfort zone..

Came across something challenging and felt that you didn't have the ability to handle the task at hand?
Definitely something that is happening to me right now...
Yes studies is one of them,added on by acapella....the feeling is really horrible you know?
To be honest i am more troubled by acapella right now.
I have been more or less chosen to take over chengyi to sing bolero.....
haven't heard of bolero by DBSK??
Well,just type "bolero dbsk" in youtube and you will know how it sounds like....
yes.......the notes are dam farking high ok!?
And i also have pitching problems,where by people singing beside me,i get affected by their pitch and i follow their pitch instead,thus going out of tune.
Hate it man......don't know how to farking improve....sibei sian.
Projects are starting to roll in already,and i also found out something bad.
With my current 3.35 gpa, teacher said that it will be very very hard to hit a 3.8gpa by the end of my poly life.
Dam i really wanna go to uni,actually i dont really know why i wanna go there,but i want to have the qualifications at least,so that it will be easier to land on a good job in the future.
I really don't know what is wrong with me,i have the feeling of panic attack,like something is going to happen or what...
Perhaps this is leaving your comfort zone,where by you face new things and challenges,but you would just like to hide below your blanket and stay there forever?
Don't know what to do.....haiz...wish i can talk to someone right now....anyone....
