> the more I realize that nobody cares about your health as much as you do

This is going to be true in all medical systems, and really in all systems for all fields.

No one else (other than maybe your immediate family) is going to care as much about your situation as you are. Any doctor, in any system, is going to have multiple patients, and they will care about all of them. You, an individual, is going to care about your own life because it is the most important thing to you, and you aren’t splitting that amongst many different patients.
