You’ve probably come across the belief that bullying builds character. I have, and having been severely bullied in school, not just by my classmates but also by some teachers, I can confirm it is a lie.
Bullying did not build my character. It only built up my anger and resentment, and gave me PTSD. Not severe PTSD, but still PTSD.
When I mentioned this online, someone responded with the following insightful remark:
Suffering does shape character. The idea that the result is always going to be positive is absurd.
The only character bullying builds is that of a sadistic bully. In those not of that bent, it damages them. I still occasionally desire revenge on the ones who bullied me.
