Who else tired of an elder's selfishness? My grandmother has always been self centered, greedy and cheap. She is a Slovenian Jew to the nth degree and can make a half penny scream blue murder. Next month, she is going in and getting her other knee replaced and has really ramped up with a Kindle Fire and an internet connection but I am the one who has to pay for it. There are plenty of options, cheaper options. But she wants a Kindle and someone to troubleshoot the thing. I'm sick of her me first and the gimme gimmes and refusal to pay for anything. Won't hire somebody to help her clean the house, keep her yard looking good and my family can't go over there once a week any more due to things we have to take care of that doesn't involve her stuff.
I'm so sorry to hear how you feel. I know its not easy caring for an elder. Its hard to be in the trenches every day and not start to feel resentful and angry. Being the go to person for everything is overwhelming.
I think our grandparents are a different generation. My father was older when he had kids and he too hated to spend money. I was the oldest so I cleaned the house, maintained the yard, paid the bills and got whatever was needed done. The years catch up this and we become tired of the norm.
If you can try and get some respite care. Take some time away from your grandmother. She is not going to change at her age.
Thinking of you. Sending love and hugs.
