Why does this have to happen now?

Okay, for those of you that are really close to me you already know the prediciment i'm in concerning my youngest brother. You also already know how my brother that's a year younger than me acts towards me as well or if you don't its prolly cuz i'm ashamed. But anyways.... apparently it's my fault, on top of all this, as to why a friend of mine is going out with another friend of mine and i had nothing to do with it.... in fact, before i met a special someone i had feelings for said friend as well.... all of us became friends and started hanging out about a month ago and last week i asked my female friend to join us an now she and the guy friend are going out and apparently it's my fault that another friend's chances with the guy friend are ruined.... high school shit is stupid!!!! i had nothing to do with it i don't set ppl up and to top it all off she's accusing me of having feelings for the guy when, we've both come to realize that we think of each other more like family.... albeit extended family but like family.... aye thats all for now.
