Hang in there. Today's "medical care" typically assumes the patient knows nothing and should have no say in their care. The timing of care items, such as meds, procedures, etc is often at the care provider's "leisure"
There are exceptions, but being prepared for this will help you understand and work with it.
That being said, discussing your concerns with your doctor and requesting a "Patient advocate" can help streamline expectations and performance.
On the flip side, a bit of stubbornness can fend off the sense of helplessness and can be therapeutic for you :)
If you have qualified and able folks to help, recovery at home after the first 3 days seems to be much more pleasant. I've been on both sides of that multiple times.
Enjoy your family and friends, be as pleasant to those who are concerned about you, and wear a SMILE at least 90% of the time, no matter how you feel.
You're not a kid, you are no doubt experienced at sacrificing for your loved ones. While they care for your physical health, do your best to care for their emotional well being and stress levels.
Not being smart alec or preachy, just sharing a box load of experience that you may be able to put to good use. :)
May the Good Lord grant you speedy recovery and comfort.
