Edimburgh university admission, requirements and dyslexia

Hello guys, i'm coming from Italy!
I'd be interested to study classics to Edimburgh University!
It's always been my dream since i was a child!
One year ago i decided to study economics in my country, but i understood to have done a mistake, cause i love the classical literature!
Do you know if there're any kind of possibility to be admitted to Edimburgh University even if i haven't taken good result in my high school.
I finished the high school 4 years ago, in a different country, and not in Uk!
Do you think that the university will take into consideration the fact that i am dyslexic?
my problem is that I discovered to be dyslexic after high school, and I never could repair my situation!
Moreover i don't know how to contact my high school english teacher!
Can i ask to anyone else, cause i know that i should leave the contact of anyone that can tell that i'm able to do a univerisity english course
can you help me?
Cheers
