I think mine started around middle school. Being autistic, I already knew I was different from the kids around me and didn't fit in. I'd known that since kindergarten. Middle school is when I started to have the creeping realization that my life would consist of nothing once school was done. Everyone around me had dreams and things they wanted to do with their life... and I didn't. Everyone around me was starting to be interested in relationships with the opposite sex (or even same sex) but once again... I didn't.
Ironically, my high school days were some of the best years of my life. For the very first time I was beginning to feel like I fit in. I was even making friends, started getting good grades, things were looking good. Then the school board screwed me. Some things completely out of my control happened, and next thing you know... I don't get to have a senior year. Was forced to graduate early at the beginning of my junior year.
That was 10 years ago, and even now at the age of 27, it feels like that was probably the day I died. The little bit of hope I started to have was completely snuffed out. To this day I still have no interest in a career or relationship. Yet I can't find anything else to fill the void with. What else am I supposed to do with the rest of my life then? If I could have figured that much out, I probably wouldn't have ended up on SaSu, lol.
