My dad is under hospice care in his home and I am his 24/7 caregiver. He has end stage heart failure, uncontrolled Afib, and severe arthritis. He had recently taken a turn for the worse and we readily see the marks of impending death. Amongst them is that he is no longer interested in food and rarely wants anything to drink. My sisters, however, are pointing fingers at me. One stated today that it’s because I’m not encouraging him to eat in the right way. I normally try to address their idiocy with patience and an explanation. And I did that today but she doubled down on her opinion and I’m aggravated now. I try to be the bigger person but I am exhausted and I’m so tired of them acting like they have a clue and treating me as though I’m inferior. I understand that no one here can fix my family dynamics but I would appreciate some advice on dealing with them.
