I'm not dyslexic myself but one of my closest friends is and he struggles greatly with reading musical notation, yet can easily cope with TAB. He has also had problems with grammar and spelling, he's also a full-time guitar tutor so it's not exactly got in his way. I'm not sure if you do have dyslexia myself, have you had the official tests that prove it? if not then it's just your own self diagnosis, it needs to be proven so you can be sure.
