Can someone tell me how to live with Undiagnosed seizures?

People have told me that it can take years to be diagnosed and I am positive I am having seizures. Because nobody can see them they write me off, doctors included. They think I am crazy or making it up, but I know I am not. So how do I live? I try not to drive for fear of something bad happening, but my parents think I am lazy. They get mad if I ask them to drive me somewhere. They no longer take me horse back riding, so do I just give that up for years? I have tried ordering groceries online as I am afraid to drive to the store, but it is too expensive and I don't have a job, which is another issue. How do I hold down a job? What if I have a seizure at work? In May of 2010 I had to drop out of college due to a seizure. How do I go back? When I was there I would have almost daily seizure like episodes. Buses would be okay except that the closest stop is a 30min walk away, up an down two hills, walking right next to the road. When I do walk I am terrified that a car is going to hit me, not to mention that that is a long walk, especially with bags of groceries probably in the rain and cold. The worst part is that my GP doesn't believe me and not many doctors around here take my insurance, so I am having a hard time getting a referral. Pretty much all I can do is sit home and wait for things to get worse because I am sure they will. Maybe that would be better because then people couldn't ignore me. What would you do? What did you do?
