I haven't felt this way in some time...

So it's 2 am and I'm so pissed off a person can be at this time of the day.
I went to sleep after a long day wirth of practicing, exams and more practicing. at 1.45 AM, my flatmate comes home, and not only does he wake me up, ha also brought a friend. Usually I wouldn't mind, but the fact that he not for once considered that I have two exams tomorrow and have to wake up early to practice and prepare for them, really upsets me. I can't even describe how much. And then come and say that he didn't know and he "texted" me about it. You can't really count a text if it's in the middle of the night and I already said long time ago that I was going to sleep.

I am so angry I don't know what to do. I tried crying, and I tried giving him a hard time, but he's eighter too drunk or too stupid to get the point. Now I'm left with a huge head ache and only a few more hours left to sleep. I think I will cry some more.
