My dad is retired military and still wants to be in control. He can't drive anymore. I go to his house every day after work. I make his dinner and make a store run for whatever he needs. I have used all my vacation days for his appointments. It's a long commute for me to get to his house then back to mine. He has COPD, on oxygen all the time, and needs a walker to get around. He's hard of hearing and is becoming forgetful. He refuses to admit he needs any help. If I didn't go over every day and drive him to his appointments he would die. He says I'm being "overbearing." I know his health is failing and things will get much worse in the future. How to deal?
