What are friends for?

I may or may not be talking about a specific person. But, I'm just gonna summarize my rant in general. 

So basically, what are friends for? Best friend, to be precise. The last time I checked, best friends understands each other, care for each other and think for each other. Although there might be different preference at times but they will always come up with a win-win situation. They might be selfish at times, they fight for their rights but whatever it is, they stay true to each other. They don't bad-mouth or backstab each other behind their backs. If they aren't happy with anything, they'll say it straight to your face.

I guess everyone have had this feeling before where your friend/best friend became someone else's best friend. This is a real tragedy. I mean like, seriously you can't do anything about it. They just leave you for someone else. I think I've been through this since primary school until now. There's no ending to this unhappy ending. This cycle keeps on repeating and repeating, non-stop. And you can't do anything. What's happened has happened. All you gotta do is live on as it is, no matter how broken you are.

Sometimes, you just feel sad inside. The empty feeling you get when no one is there for you, or some one is but they're actually just being a busybody. Even if there was one, it's not gonna be the one you used to know anymore. It's really sad when someone you know becomes someone you knew. They judge you, they bad-mouth you, they backstab you, they spread rumors about you, they secretly hate you yet daring to act like a saint in front of you, all these are just F A K E. 

After being disappointed a million times, after your heartache from everything you saw and heard, you'll get used to it. I swear. Maybe in my life, I'll never find a true friend. Even if I did, things will/did turn bad.
