ayeeeeeeeeeen_'s Things

I want to ask for you guys opinion.. my childhood friend confessed to me that she like me since a long time ago.. I don't really like (romantically) her because she got something bad in her mind (she kinda creepy, thinking about death, and suicide, but she's a fine girl always happy..idk why, a fetish maybe?) .. and it's kinda weird to go out with someone who we're raised together.. but I don't know how to stop her bothering me.. but I still do wanted to hangout with her.. it's kinda messed up though.. I hope you guys can give me some tips for it.. (btw I'm not lesbian)
