My Junior High / High School experience was pretty horrible. I dropped out my Junior Year of High School (I still had almost all A's when I did drop out) and then later got my GED that year.
It wasn't that I was bullied 24/7 although I did get picked on occasionally. I survived by blending in and just being invisible to people. I was also very smart, and got good grades so people wanted to be on my good side so that they could get help with homework.
I had a pretty awful experience with my school due to sports. Sports was king at my school, and I did like sports. But parents at the school were causing problems at the game. Yelling at officials, getting into fights etc. It got bad enough that the school made a rule that all parents must attend a "class" where they learn proper behavior at games. Yeah, pretty pathetic right? Well my parents refused to go because they weren't a part of the problem. So I was banned from playing sports, which completely crushed me. I was then pulled out of that school, and we tried going to a different one. Well, going through depression (which my parents didn't know at the time, and I didn't either) going to a new school just made things worse. That was living hell for a week. My parents tried forcing me to go, but I ended up running away for about a day before they decided they couldn't force me to go. So I ended up going back to my original school, just without the ability to play sports. Ironically not long after that, they reversed the rule that they had put in to begin with. I was pretty upset with my parents for a long time after that experience.
I never connected with anyone at all during high school. My best friend basically abandoned me. I still had a couple friends, but things just weren't the same anymore. Everyone was trying to be cool, part of the popular crowd, and putting on face displays of who they were. I couldn't care less, and I thought the whole thing of it was sickening and obsurd. So I pretty much started withdrawing from everyone and turned to online video games instead for friends.
When I did end up being allowed to play sports, I hated it because I couldn't stand the attitude of everyone when we were doing it. It was all about winning at whatever cost, even if it came down to cheating etc.
I guess this was just about junior high, but it pretty much all blended together for me.
