I am dyslexic.

I still check my hand for left and right, I cant wear heels and mathematically - well lets just say that calculators are my bestest friends. But I was soooo adamant I was going to read and write that I focused wholly and solely on that. Despite that I will still leave out words here and there and you will find them - up to half sentences - sitting in the most random spot 2 to 3 paragraphs later.

I found reading light writing on dark backgrounds helped me a lot. The other way round I could read something 15 times and still not remember a word of what I read because it didnt make sense.

Maths just doesn't stick at all - I just can't get it. My sister spent ages explaining algebra to me in several different ways - even got me to do equations and the like. With her help I got 93% right. Doing it myself a day later, I failed gloriously.

Just a bit of background from one to see if there is anything similar.

My brother is a step worse - dyspraxic. He started teaching himself how to read and write when he was about 17 because he wanted to write a novel. He has written part one already. So even if its hard for her now, the right motivator for her later can have the most amazing effects.
