One of my friends obviously has a crush on me- but i dont like her back like that, not at all. I need help. Big time. 

One of my friends has been really obviously crushing on me for a month or two. But i simply don’t like her like that. It makes me pretty damn uncomfortable and i just don’t know what to do. Im afraid she’s going to ask me out or something, to which i would have to say no. What I’m worried about it, if i say no, am i going to end up hurting their feelings really badly? And worse so, will i end up ruining my existing relationships with my other friends because i would say no? How do i stop this madness?!?? She’s best friends with another one of my friends and I’m afraid this is gonna result in me losing that friend too, and then other friends as well. I hate this damn situation. I just want her to stop liking me. I want to just be friends.
