Do i have dyslexia please help?

Hi, can anyone help, i think i may be dyslexic, I am 20 years old and have alot of difficulty with day to day work, my reading is poor, i have to read a paragraph over and over to understand it and sometimes i dont and have to have someone read it to me, i read very slow and miss lines and words, ever worse when reading aloud, i have difficulty expressing myself in words i can easily tell someone an answer but writing it down is very difficult. my handrighting style changes all the time along with the way i hold a pen, i get confused very easily with directions and dates, i work out a soloution and nobody else understands my thinking, i am very disorganised and get easily frustrated when i cant do something properly.... does this sound like dyslexia??? i cant afford to pay for a diagnosis but have done an online essment which suggests that i possibly do have dyslexia, can anyone help, i live in scotland
