"Specific Learning Disability" - this is why I never ever ever got tested for anything. I'm a phenomenal test taker (whether I know the subject or not) and I can learn anything I have an interest in - and my interests are wide and varied.
Try talking to me about history though and I've suddenly tuned the fuck out forever.
FOREVER.
Learning things I hate always mimics my brother's pattern of learning (he WAS diagnosed with ADHD) - but I was always interested in science, math, english, creative writing, sociology, psychology, art, language - these things fascinate me. Give me a history book though and I've suddenly read a page 16x and have no idea what it said. So the older I get the more I think that he and I probably struggled with the same thing but I lucked out by having much broader interests in knowledge that correlated to things taught in school.
And where he would tap a pencil or make noise to get rid of his twitchiness? I did silent things that couldn't be tracked. (Like squeezing my toes in patterns which is impossible to see with shoes on.)
