Probably a bad combination of genetics, an overprotective dad, no kids other than my brother in the neighborhood, and going through most of elementary school with the same 16 other kids.
My grandpa got really bad anxiety problems as he got older, leading to stomach issues, making him quite the *******, TBH. He eventually decided to just stop eating and pass on. I'm scared that I'll be like him and change into a completely different person nobody recognizes eventually.
My dad is slowly turning into my grandpa--to the point of stockpiling soup for WWIII just like grandpa. When I was little nobody could ever do anything because if we weren't home when he decided we should be we were kidnapped and/or killed, no exceptions. He still thinks this way and I'm 17 now. I couldn't even take swimming lessons because I might drown. Counter-productive, much? He also loves injecting himself into everything and therefore making things more painful than they should be. When the time comes he's going to a nursing home. Like grandpa.
In first grade I got to take a special test that put me in the last year of the district's gifted program. (I was in the last year because they wanted to get the money for it without actually having it.) I didn't really want to go, but I decided to since my best friend was going. Five years later at the end of sixth grade there were 17 of us, total, from what was a full class. Most of them left because two of the three teachers we ended up having were two of the dumbest, meanest people you could ever meet. It certainly didn't help meeting so few people my age in that time, nor did those two treating me like I was retarded. Halfway through sixth grade the teacher decided that a C was never, ever, under any circumstances, acceptable and was as good as an F, and a B was decent sometimes. (She was very similar to Dolores Umbridge in Harry Potter and that was enough to make want the centaurs to kill her. She (the teacher) couldn't teach and expected us to know everything already.) Later she tried to convince us that 7th grade would be as harder than my teachers are currently saying college will be. All she really taught us was not to trust anyone and never do anything social.

I actually managed to write an essay for my freshman english class about just how bad those two teachers were, without going into how much they're still affecting my life. Got a very high grade; 98% IIRC. It nearly hit the upper size limit.
But back on topic, I can't look any of those 16 other kids in the eye any more and not remember that torture.
Some of this probably makes no sense (forgotten details, misplaced stuff, etc.) or is completely off topic but I'm tired and have a headache and I just don't care.
tl;dr My biggest problems all boil down to extremely limited socialization when I was young.
Edit: You could say bullying hurt me. It wasn't from other kids. Those two teachers were bullies in every sense of the word. Those anti-bulling campaigns teach us how to deal with kid bullies (which I luckily never dealt with), but what do you do when your teachers are the bullies?
