I have sons and luckily have no real health problems [I'm 71] but do get the odd bad day when I feel rough, and have different niggles now and then.
My sons are both healthy, so have no idea what feeling unwell/having an operation for eg. feels like [bar the odd bad cold, pulled muscle etc]...and certainly no clue about how it feels to get older and feel the body changing. So I'm very glad about that. They have always thought of me as Superwoman, it's a family joke...apparently I can do anything, I am in this world for them, can do everything myself, not at all needy etc.! and they tell everyone that. And of course I am always there for them.
It's because I live on my own happily and am very independent, never ask for help so I have given that message out for decades now. I know they are not responsible for my health and welfare but if ever I have been in trouble in previous years they have both been there and attentive...it's take a stint in hospital to do that though! Just not the rest of the time.
I do however explain to them now and then if anything is bothering me health wise just so they are aware, to make then think a bit. And I let them know that if I can't see them or babysit etc it's not because it's what I want but that anything which stops me seeing them or the grandchildren upsets me a lot.
If I was you OP, I would take the above advice of saying you are saving them from harm, waiting for test results and anyway a period of self isolation should make your DD appreciate you much more. Do not mention your feelings or how hurt you are feeling, deal with it yourself or it could make matters worse. One day you may be able to communicate your own needs to your DD calmly, aside from this incident.
