Dear Hou Ting,
     I am sorry that maths disappoint you, but you can't give it up.
As you say, it is one of the most important subject and there
is a reason for this. We have to use maths from all the time.
Wherever your career takes you, maths will have to be using.
In fact , most employers and universities will accept people
have failed or given up maths. All you can do is try your
best in maths and make the most use of time you had. If you
have trouble understand anything, the first person you should
tell is your teacher. That is often surprising how simple things
seem when you are explained properly - even maths problems!
