It shouldn't start from the beginning,everything was wrong...I'm quite tired of it,may be this kind of thing didn't suit me,I can't stand anymore..What I need to do is stop it as soon as possible..I'm regret to do it and try to go back to the right way,but I didn't do what i should do and keep jump into this big hole....But now,I know I can...Just need to be tough to face it...
