I am a dyslexic. I was diagnosed in first grade at the age of seven, I am now 43(in two weeks) I have learned to live with it very well. If I write letters I use a dictionary to check my spelling. On the computer I use spellcheck (which I highly recommend) I read all the time. Having a disability isn't about what everyone around you makes of it, It's about what you make of it.
Having a learning disability doesn't mean your stupid, it just means you brain is wired differently for processing information. Most people with learning disabilities are rather intelligent.
