Ahh.. why do I feel like this?

There is this GREAT girl that i met at the beginning of the year and she is so nice and we have so much in common it is like a miracle we met each other, like, shes from Korea, and what are the chances of finding someone else who listens to Korean music and watching anime and reads manga and draws manga like her? (lol) so we were becoming friends really fast because she didn't know anyone else in homeroom, and then she met Katie. Here's the problem, she is really shy so i am SSOOO glad that she met someone else, but at the same time i seem to hate her(Katie) ! You don't even have to tell me i KNOW that i am sooooo jealous of how Katie can make friends so easily. I feel like she just stole her away from me. But at the same time i feel SSOOOO bad because i really love Katie cause she i so nice and i know that i have no right to hate her or be jealous of her! I really like her too, I just really want to get to know that other girl really well. How can i stop feeling like this, becuase I know that she has done nothing wrong i just can't help think that i wish she wasn't there?!?
