What is wrong with me?

Ok seriously I'm always feeling down and easily annoyed or angered. Is there something wrong with me? Or am I just having a hard time? Smiling seems kinda alien to me nowadays, and I still hate that old man. Its easy for me to forget what you did for me but hard to forget the bad stuff you said. I won't forget ever! But holding a grudge doesn't bear me any good. Seriously, how does holding a grudge solve anything? But then I just dislike the fact that you're pretending nothing happened a tall and trying to seal back the wounds like I'd forget what happened. It won't be so easy you bum, if you wanna make me forgive you start changing yourself first. Likewise I'll not talk to you for a while. So be it.
