Friend Drama
If the drama of your friends' annoys you, stop worrying about it. Do not let their problems, only if they are minor but your friends are blowing them up, cause you stress in life. There is too much of that already with everything else going on in the world they don't need to add on. Now if the drama is something that does deal with you then maybe you should talk to them about it and try to get things resolved. If that doesn't work then it's time for tough love, so tell them how you really feel and do not sugarcoat it. They'll be better off for it and might learn to calm down.

Now for those who start the drama...Stop It. If it's something little and really not that big a deal, then why are you so upset about it? That's right, this whole thing started over something stupid and has now escalated into this big thing that is probably pushing you away from your friends, who you so graciously pulled into the middle of it. No sit and think, is this really something you wanna argue about or is it time to just be the bigger person and just end it. I can't tell you which to do, but i can say that if everyone you talk to looks annoyed about having the conversation with you then its probably not something worth arguing about.
