I guess I'll buck the trend in this thread. I was bullied relentlessly. To make matters worse, not only did some teachers and faculty not do anything even in cases where it was apparent, there were some cases where they themselves contributed to some of the bullying. Even when that wasn't the case explicitly, bullies tend to be smart enough to push you to the breaking point just out of a teacher's view so that when you snap, the only one getting punished is you and since there's no way to prove that the bully started, you feel like you're getting punished on both sides.
Suicidal thoughts were nearly an every day occurrence for me. I certainly developed the kind of anxiety where if I heard anyone talking or laughing, I knew it was about me.
BUT
My college basically changed everything in my life practically over night. No longer was I mocked, beaten, or made fun of for excelling or working hard. Within my department I was lauded for it. Oddly, despite feeling like I was an introvert, I really was an extroverted guy in many ways.
I basically became very popular overnight in college. Things about my personality that made me unpopular in HS made me very popular in college. The problem was, I attended small town schools where there is an "old blood" top down hierarchy of who is allowed to be cool. I was not allowed to be cool as an outsider, so nothing I could do helped.
But in college, I was the cool, outgoing, compassionate guy that bravely gave no fucks what anyone thought. I'd developed a lot of empathy being the butt of the social totem in HS. I'd also realized somewhere in MS that trying to act cool would just backfire, so I stopped hiding my interests in nerdy things (can you believe games were uncool back then?) and my willingness to work hard at music.
And to this day, I still don't give any fucks. I don't have any crippling anxiety. I have almost no social weirdness. I'm 33 and my life is fantastic. The only thing that really bothers me is systematized mistreatment of people. It makes me irrationally angry and very uncomfortable. I can't watch movies where people get trapped in a foreign and country and nobody believes who they are. Government and police corruption and abuse of power make me very agitated, which sucks in today's zeitgeist.
These things just remind me way too much of the bullshit I got from teachers and faculty more than by students. I hate feeling like the people who are meant to protect me and keep order are the ones doing the most harm.
But is that because of my issues growing up? I'm sure it makes it hit closer to home, but I figure that most people feel this way whether they were wronged by teachers growing up or not.
So yeah... I just am not suffering long term from my bullied childhood.
P.S. Bonus... I had an abusive, alcoholic step-father who never valued anything I did and was psychologically and physically abusive quite frequently.
TL;DR - Really rough upbringing with tons of bullying from students as well as teachers in addition to abusive step-father at home. Totally normal, happy, socially outgoing, 33 year-old guy with above average ambition and personal self-motivation.
