Beth, I think you can still purchase insurance. The only thing it won't
cover is 'pre-existing conditions'. So assuming your mother's health
'under control 'at the time you purchase the policy, you should have no
problems. Most insurance companies send you the policy when they receive
your payment, which you should read carefully, and you have a week to 10 days
to decline it if you feel it is not what you want.
And for your car, don't forget the coverage some credit cards offer.
