The cliche on why bullies bully: "Oh it's because they're insecure and unhappy", as if this is supposed to make the victim feel better.
But it's hard to think like that when you were the kid with no friends, being bullied by kids who were popular and well respected. You start to kinda think "you know, maybe I do deserve it".
Like when I was in high school one kid told me to "get a life", so I responded with "you get a life!" And she said "um, I've got one, thank you", and skipped back to her large group of friends who were all laughing and joking with her like they were all having fun. As I stood there on my own I just muttered, "touche", feeling so hurt, lonely and unliked.
This is why I don't bother getting reassessed even though I still doubt my diagnosis. I mean, to be as lonely and worthless as that in high school, there's not a snowball's chance in hell that I'm allistic.
NO, NOT saying people on the spectrum are worthless, but it's still sadly quite normal for people on the spectrum to be treated like I did by their peers at high school. Well, I think I was too lonely even for an Aspie. Other Aspies have better social lives at school than that.
