Driving with Epilepsy

Hi, my name is Cameron and I was thinking of getting my unrestricted driver's license. But here's the issue, I am 18, and have had epilepsy (Traumatic Brain Injury) since I was seven months old and when I turned sixteen I went and got my permit and now I am eighteen and still have it. Is this common for people like me who have this condition take this long to receive their unrestricted license.
