I started caring for my 77 yr old father about 9 months ago and he is now living with me. Due to his health and some minor cognitive issues he can't live alone, drive, attend doctors appointments etc. I'm 37 and I'm finding it difficult when I have to tell him no or when I have to intervene in some of his decisions. Most of the time it is due to him being impulsive, not great at budgeting his money, being stubborn, and other times he is just unable to think clearly. It's like a mix of his normal behavior and his decline in health adding to his inability to make rational decisions. He is constantly trying to do things he is physically unable to do. He has a limited income, no savings, and was blowing through his social security check in a few days. He had always been very independent and a bit stubborn. I know this has been a difficult adjustment for him. I find myself having to constantly tell him no and he even says he feels like I'm acting like his mother. He will be passive aggressive at times and it makes me feel guilty. I never talk down to him or treat him like a child. I really try hard to make him feel included and informed on all decisions.
This is my first time posting so it's a bit of a rant and a request for any advice.
