No, scars imply you were wounded and you still bear marks. Nothing more.
It is an attempt to pass off your reaction as not legitimate, yes, because it's not. I'll say it again - you didn't have to be there, nobody was forcing you to be in that classroom, that was your parents choice. The only choice they didn't have was not to educate you at all.
--edit-- Further on the scars thing - in your first post in this thread you explicitly talk of emotional abuse and deliberate traumatisation during your schooling, I'm not sure why you would think my suggestion you talk to someone about this is so offensive?
As for "deliberate"? Deliberate's got nothing to do with it. See also "The Yellow Wallpaper".
