Bad mood

I've been in a very very bad mood for a couple of hours. I don't know why, but everything seems set to piss me off. It happened yesterday too. Facebook's pissing me off, I was just in a multi-chat with a few people, they all left because I ruined it for them, and I assume they're now in another chat thing without me there to fuck it up. That doesn't exactly feel great. what's more, I don't really have anything to do; the only offer I had to do something happened when I was busy with homework. Everyone who was in that chat thing joined a group called something like 'i think he's on his period', which I assume relates to me and is also fucking annoying. Someone who usually pisses me off a bit, who I won't name, was pissing me off a fucking lot a bit ago. I don't know why I got in this mood, but it happened yesterday, is happening today, and so I assume it'll happen tomorrow too. I hope it doesn't; I may be around people then, and I don't want anyone to see me stropping like a fucking five year old.
