Judy, when she is really pushed to the wall it is up to her to either sink or swim. Others have been there, some are still fighting the good fight with no one to care for or worry about them. Its something we all may have to face from time to time, and she is going to have to pull up her big girl panties and forge onward. She is not your child, she is an adult friend, encourage her all you can BUT do not become a crutch. She needs to hit the water and learn fast to swim... Pray for her, that always helps.
