An Emotional Time

I have been quite emo as of lately. The history is that one of the people I despised most (and I will stress that I don't despise people easily) came over to my house and ordered around as if he is King. Actually I haven't been angry for quite some time already. I remembered the last time I was angry was in grade 11. But yet I was not really angry that time. So you can say that I don't remember the last time I was really angry. I can't even recall I've been really really angry like this time. (if angry was the emotion I experienced at all).

Sorry, the writing is a bit crappy. I'm not really into typing things that need to be thought before. I just want to express my so called angry feeling.

Anyway, even after two weeks, if the topic was brought up, I still feel the same way as before - be it anger or not. Let me describe the emotion:
1. My head becomes really hot.
2. Afterward I got headache
3. My breathing becomes heavy
4. I cry
5. I feel destructive (want to throw and break things and hear the breaking sound).

But the weird thing is...
I'm not sure why I was so angry, what I was so angry about. It's just that I feel like being angry that time.

Sucks...

Even now if the topic is brought up, I might end up feeling the same emotion, which I'm not sure about. Is it anger? Is it something else?
