Haha dude, all I can say is that there is no quick solution to this problem
Go slowly bro, get her to feel comfortable with talking with you for a start.
Just wave and say hi or good morning etc.
Don't overdo it though(I.e going out of your way to say hello to her all the time), you'll want her to become comfortable with your occasional presence.

I don't wanna say anything more and lead you too far ahead just yet.
Just little things, don't go looking for her, let chance and fate give you opportunities!
