I'm capable of punching you without prior notice

I get pissed whenever I hear my mom's angry voice. Trouble with her and my temper is that the second somebody triggers it, everyone will get it. I mean everyone. There was an incident in primary school when I pushed to the sidewalk a kid who didn't do anything to me except the bad luck of walking past me. There was another day when I kicked my little sister for nothing. I didn't meant to connect the kick though, but I did. I thought the damage to her was irreparable physically and mentally. I know I'm already mentally damaged but it's better to not share the pain.

I should get into anger management... but only if my mom joined me.
