Did anything *physically* happen over the weekend? Bump to the head? Or I suppose it is possible that the stress you're under caused your symptoms to recur.

When I did my vision testing, the doctor said that problems with field of vision can indicate brain damage AND actually what location in the brain is damaged.

It really sounds to me like you should get checked out and not try to push through this. If you don't feel safe driving to your doctor's office, and there is no one at all to help you get there, consider calling an ambulance?

Hope you're feeling better soon. I'll be thinking of you.
