I have siblings that had distanced themselves physically and emotionally from the family for well over 20 years. There has been no relationship or contact to speak of, between my siblings and parents, and for good reasons. Siblings some how found out that our parent has memory impairments, and now trying to work their way back into the picture with their agenda being of greed. I am financial and medical POA. I have been the only child that for many years has been the primary provider of care, doctor visits, arranging for care, helping with all of their needs. I have always had a close relationship with my parents, who chose to sacrifice time and energy, out of love and respect for my parents. I am offended and upset that in the "end" game, siblings that have never shown any concern, and have never contacted parents throughout the years are now trying to come around to involve themselves with a vulnerable parent. How do I handle this? I'm sure this is very common in families, so any advise would be much appreciated.
