Fuck, you're so fucking selfish.
Yet I don't know why I always give in to your mood swings.
As you can be the sweetest person on earth you can easily transform into the devil himself.
AND SOMETIMES YOU ARE JUST SO STUPID THAT I ASK MYSELF HOW IT IS POSSIBLE TO REACH THIS LEVEL OF STUPIDITY.
I tolerated so many things because you are my friend. And I bet it's the same for you. Sometimes I remain quite so I don't hurt your feelings. I don't want to hurt them if not necessary. But you really push me to the edge at some times that it makes me want to punch a wall. I try to keep my cool but hell you make it so hard for me sometimes. 
And it's because of your stupidity that we get in arguments. You will never admit that you're at fault but if there's evidence or you feel like you should. Not when you're angry though. And even then it's ME who should be angry. Why the fuck am I still friends with you? You should have never tried to befriend me. I wish I had never met you. I wish you never existed in my life in the first place.

You can be a real cruel human being. Using people as you feel like. Using them like they're a fucking tool yet you really have the guts to say that you're sick of getting hurt. Is that why you also want to hurt others? Use them like they're puppets? Act like you're not going to break their heart? You're a fucking narcissist. I told you that doing this kind of thing will only make the person who is in love with her profoundly sad but all you care about is using them to get what you want? You know what? You deserve to fucking cry. It's not my judgement to make but this is the way I think about this whole thing. As you like to say "karma will fucking get you, bitch."
