An Italian friend of mine was widowed at an early age. She remained in England and brought up her two children alone. When her mother became frail she brought her over to England, and cared for her for many years, until she died. Some years later, although her own health wasn't too good, and her eyesight was failing, she brought over her widowed sister . Her sister had no family in Italy to care for her, and she had cancer. Gina looked after her also, until her death two years later.
This is the Italian way, and they would be astonished at the idea of not caring for family members, no matter how difficult it is. It used to be like that here, as well. I know that it still is, to some people, but many aren't willing to compromise their own lifestyles, and expect someone else to take the responsibility.
