Here is the girl,whom i love thoroughly.She is in my mind the whole day,she doesnt know much about me,but she is career oriented and tends to avoid me.She earns handsome.and i m no one in front of her.How to make her feel the way i feel.I am not able to stop my feelings for her now.What should i do?

Hii mate,
The only way u can attract someone to you is by befriend with her, try to understand her and support her for her decisions and also give her an opportunity to know u better u may then go for conveying ua feelings infront of her, remember, the first step to a successful relationship is friendship, which may grow deep into love, with time and understanding....

Swapnil is right..
Is she in your office, on higher designation than yours ?
