I think with me it's due to suffering in silence in my early high school years. Around the age of 11-14 I was often randomly picked on by kids and I just ignored it and never reacted. I was just seen as a weak wimp who wouldn't say boo to a goose, and the bullies were like "she's so easy to target, she doesn't even get upset!" Yes - believe it or not most bullies don't want a reaction, and if they do just want a reaction then really they're probably not that artful. Real bullies could spend years bullying you whether you react or not. If you don't react they still get a kick out of bullying you. In fact some bullies get so frustrated that you don't react, that they would go through hell and high water to cross the line to actually make you react, like physically beating you up or worse.
I wish I had of reacted more back then. I did in my later high school years, but then everyone just called me an attention seeker or they played the victim. You can't win either way with bullies. The best way to not be bullied is to have friends and be popular, because bullies feel threatened by groups, and even if you are still being bullied despite being popular, it's easier to deal with or to hold your head up high and not let it get to you. But that is something I'll never, ever be, so it just makes me an easy target, and naturally I will be more sensitive to it. Being bullied can make you feel isolated and hated. I hate being bullied.
