I have Cerebral Small Vessel Disease - so far caused loss of balance

I have vascular small vessel disease that so far just has caused a severe loss of balance. I walk with a cane, but it is getting harder. Likewise exercise is not easy. I still drive short distances. I feel perfectly normal lying down and it is so much easier to do that. The sad part is I don't really see anything that is going to end this as otherwise I am healthy. I know there are many worse things. Does anyone else have this and how are you coping?
