I got in a bunch of fights back in elementary school, never started one myself, other kids were just starting shit with me for no reason (even back then people were already messing with me, jfl), suprisingly I won most of them, and of course got punished in each case as much as kid who attacked me.
Then three faggots had it in for me and rest of elementary school was just me getting beat up, rest of kids laughting at it and teachers punishing me for "getting in a fight" JFL. Now that I think of it, it was probably during that time that any of little confidence got shattered and my first mental problems started.
Also, did I mentioned that I hate education system and anyone who willingly becomes part of it should get typhus? Well, I'm mentioning it now.
