My dad is 79, will be 80 in 2 months, he has had a lot of health issues and has been in and out of the hospital. When I got home from work last Saturday he didn't know who I was and had one shoe on. He went into the hospital and was transferred to a nursing home. His blood pressure was dangerously high because he was forgetting his medications when I wasn't home to give them to him even though I called multiple times to remind him. I can't afford to quit my job and stay home with him but he keeps saying he wants to go home. I do t know what to do!
Is he able to be on his own otherwise, i.e. fix his meals, get to the bathroom on his own, and generally be alone when you're at work? If so, then a nursing home may be more than he needs, if you can get his medication management in order.
If it is memory issues, when your Dad says he wants to go "home", chances are he wants to go back to his childhood home, back when things were easier and happier.
If you were reading this about someone who was a stranger to you, not your father, what would you think? You would probably think this is a no-brainer.
Any decision regarding our family is probably the most difficult to make. We constantly second-guess. Good luck with whatever you decide to do.
Tell your sister to back off unless she's willing to be with him during the day.
