Just had a tiny mental episode.
It had been building up for about two hours. My cat being in heat and quite obnoxious (not really her fault, I know) just added that extra bit of pressure that made me loose it.
I'm not sure what happened exactly, but it was bad enough that bit my own hand at one point. No severe wounds, though. Normally feelings like that don't proceed into actions, but sometimes they do. It scares me a little bit, because this happened when I didn't want it to happen. There's a high chance that there's going to be circumstances where I do want to inflict harm onto another person for some reason or another, I fear what will happen when there are no boundaries.
I needn't specify this, but the cat wasn't harmed in any way. In fact, I put her out of my room during these events.
