Last week, I got really, disproportionately mad with my family for some reason I don't even remember. Kicked the door off the bathroom, smashed bits of my computer, and kicked a bunch of stuff that wouldn't break. After the door - I didn't expect it to actually be damaged but it came off the hinges; I settled with beating myself over the head.
This isn't right, looking back it's really scary. I know I'd never hurt someone but when I look at behaviour like that it makes me wonder. I fixed what I could and no ones said anything but the damage is pretty obvious. I don't think I was trying to get at my family because it was mostly my stuff I attacked.
This is getting more frequent, and it's worrying me.
I don't think when you have rage like that you need to let it out though. I think if you leave it it just goes. Or excersise maybe - like if your feeling rage do some press-ups. I think that you can be strong, bite your lip, and instead of shouting at your mum, walk out the room. Maybe tell her in a calm conversation what your gonna do so she knows not to follow.
Try not to smash stuff up, it often turns out really useful later.
Try not to hurt yourself, cos that's just not good.
