This has been bothering me for some time now.
My Dad has multimorbidity, i.e. numerous health issues that can be treated by being a self-advocate, and not giving up (it's easy to feel discouraged with lot of pain from illness, medication side-effects, etc).
66% of Americans over 60 and 25% of Americans over 80 have multimorbidity. As you notice, the numbers shrink as age increases because people with multimorbidity are lucky to see their 80th birthday.
We both visit the same Family doctor who is rather concerned that I don't have a life outside of working and taking care of my Dad.
While being a caregiver is draining, I know if the shoe were on the other foot, my Dad would do the same for me, even though I am over 18 years.
I am also trying to get strength from such a horrible situation. For instance, more time away from people (other than my Dad), means I can sneak time to learn new languages, for instance.
When I am being reminded of what I am not having, it is rather discouraging.
How to politely tell the Family doctor that I am content to take care of my Dad, and I trust in God's timing. Who knows, maybe God wants some people to have friends, social life, marriage, children, while he wants other people to live solo!
