I'm in my 40s and still think about this daily. Bullying is misleading as it rarely got physical - more continual rejection, mocking and frequent humiliations over having "no mates" and generally not being liked.
I don't hate those people, as bad as some of them were. I hate myself. I want to punch that idiot in the face. Being needy with bad social skills was asking for it at a NZ secondary school in the '90s.
In the final 2 years I forced myself into a group of less popular individuals, but this was nothing like a nerdy group of friends who have each other's backs, as portrayed in the media. We had nothing much in common. I was tolerated.
Because of these experiences nothing seems real now or counts for much. There's few opportunities to prove to myself that I've changed, and the politeness of older adults seems fake. Teens or early twenty somethings might be obnoxious but at least there's honesty there. That felt like reality, this doesn't.
