minxie it is a shock. My friend had a full blown stroke this time last year, and was told that she had had a number before. She initially has no swallow reflex, couldn’t walk had no use of one of her arms. A week later she tottered out of hospital, and has been getting gradually better. She is in Hawaii at the moment.
So I think on the whole you will find it is ok and not so bad after you get over the shock. If you feel that your eye sight is ok, I would definately push back against the driving ban. It may in any case be only until you can be properly assessed.
