My mother passed away 2 years ago. I took care of her for 5 years after my father passed. She bought the house next door to me. She had COPD, never drove and relied on me for most everything. My one sisters son's never even saw the inside of my moms new house. My sister passed away this past November. They are now splitting my sisters share of a nice size inheritance. I don't want their money, but am having trouble with thinking they don't deserve it either. Am I wrong for feeling this way?
