I had some problems socializing since I was in pre-school when I was only 5, but I had to change school when I was 11 and this new school I went to was full of wannabe thugs, one guy who studied in the class right next to mine was killed in a bottle fight in the same year.
I was beaten by said thugs mercilessly lots of times but the worst of it was when I was 13, starting back then I isolated myself, when I was 17 I found out 2 of my classmates were arrested for beating a tire repairman to death just for the hell of it.
I began working I was 23 but I improved very slowly, only when I was 29 I could say I became semi-functioning. Brb being surrounded by wannabe thugs and real deal killers was no good for my mind.
Not sure, feels like I was always like this. But looking at it realistically there would have been things in my childhood that precipitated it. Even from an age as early as five years I had a reputation among my parents and teachers as a gifted child and I had a dim awareness that the other kids around me were all somehow dumb. The awareness was dim because I did not really connect with my peers. Things stayed like that until the years leading up to me entering high school, where I started to notice that everyone around me seemed to be growing up and maturing faster than I was, and I began to fear that they would overtake me socially. That was probably what did it. I remember crying when year seven was over, knowing that things would never be comfortable in that way again.
