Can you lovely ladies try and cheer me up?

You probably know i am infatuated with this girl at work because i told her i had fell in love with her when i knew nothing about her. Today i tried to tell her how sorry i am. I approached her and said "can i have a word". She replied "NO, i dont want to talk to you" in the most awful way. This made me realise that the girl of my dreams is not who i thought she was. She may be beautiful on the outside but she is ugly inside.Problem is i have built her up to be some sort of goddess in my mind but in reality im not sure she is all that nice. I am so upset and i know you will all tell me to move on but its too hard. Even though i am starting to dislike her i am drawn back to the thoughts in my mind. I am really upset with this situation and i feel like my life is over before it has already begun. Can you ladies try and make me feel happy again. I know now i am worth more than this girl.
