My older sister lives at home with my dad, 91, and deals with most aspects of his care. Carers call in 4 times a day to assist with continence and going to and getting up from bed. I am there a few days a week to help with everything. This would be a whole lot easier were it not for the unpredictable nature of my sister. She had a history of drink and anger, and while now she behaves better, I am always on edge around her. She tends to make it difficult for me to leave the house, and makes drama about little things. Her and dad have never got on great. I have frequently been stuck in the middle of their arguments, both trying to get me to side with them. It was the same for my mum, and then she died. I try to keep myself sane, and have a husband, partner and stepson to go home to. But on the days I am there, I come home feeling tired and depressed and just want to go to bed. Sometimes my husband takes over for me. At the moment, my sister and dad are isolating as she had been in contact with someone who tested positive for covid. Today I dropped groceries into the porch, and spoke to my dad through the window. Dad gets little tantrums sometimes, as he has had minor strokes. It never lasts very long, and the best thing to do is remain calm and listen, he is always remorseful afterwards. I know its easier for me as I'm not there all the time, but my sister is a very reactive person anyway. This had happened today and the two of them were at loggerheads when I called. Both were trying to get me onside in front of each other, they were both calling each other names, like children. I tried to mediate in the short time I was there, but I had to leave as the cold air was blowing through the window and I didn't want my dad to get cold. My sister says she has called the psychiatric doctor to come and assess dad tomorrow. But I believe that my sister is also to blame for her reactions, and her speech was slurred so I know she has had a few drinks. I am feeling very sad and helpless, and I know I would feel this even if I was able to go into the house, in ways it might be worse as left to their own devices they will probably sort it out. But I am concerned for my dad, as I feel like my sister is also blaming him for her own stuff. Is it elder abuse? I have had to report her in the past for angry behaviour towards my dad. I am also concerned for myself in dealing with all this. Thanks for reading, sorry so long.
