I guess the worst part about not owning a vehicle is depending on someone else. I can still drive, I sold my truck, then divorced and it left me without a vehicle.
I either have to use a taxi service which is expensive, 12.00 for two miles or hope when I call one of the kids, they show up. It actually is pretty stressful for appointments, I try to use my insurance coverage. If I needed to get to the ER, I would have to call EMT's which I am not comfortable doing.
I have survived, managed and will keep on keeping on, it is better not to drive if you feel you are not able than to risk a serious accident. Hang in there babies, it will be fine.
