I had quite a temper younger, I think it started around 2 yo, I was getting so mad that I stopped breathing. Later I started throwing stuff through the window. I also destroyed a few walls and ikea drawers. I'm calmer now, but I swear a lot at home, especially at the computer and sewing machine. I usually behave in society and don't get mad over silly things but in some rare occasions my old self came back and it surprised everybody including me, it was like hearing someone else talking, like if I was possessed.
For example: I got super mad at someone in a car for ignoring the red light, pedestrian light and trying to pass while tiny kids were crossing the street, I yelled at that person so much and may have kicked their car as well, I experienced a kind of blackout, so I don't remember, but everbody was looking at me with their mouth open not saying anything. It also happened when I was riding my bicycle and stopping at an intersection and a guy also on bicycle decided to ignore the stop sign and hit me, then had the nerve to yell at me... I just saw red. The police arrested him, while I was yelling at him as well, for another crime. Then there was that time when little idiots threw stones at my dog, another traffic incident, and once I threw a customer out and when the boss came, because the customer complained, I told him to shut up and he said "ok" and ran away. I rarely get mad but when I do I get scary. I also almost turned into an evil spirit when I lost someone and tried to hit people but I don't remember, another blackout, and that scares me, what if something happens and I lose it again?
Luckily, it didn't happen in the recent past years. All those (rare) times words were flying from my mouth before I realized it and I was "Oh my gosh, what did I just say?", and those blackouts, it was like waking up in the middle of nowhere not knowing was going on, super scary, I hope it will never happen again, it really felt like being possessed. So I'm tring to vent often to avoid outburst event if I rarely get really mad. Most of the time I'm just a little annoyed and forget about it right away.
