Well navigated and interesting post as usual bro ❤️...
The work of a caregiver is always Very stressful indeed. So sorry for that Friend of yours who experienced an accident and couldn't be able to walk, eat kr even use the restroom. Right from the illustration about the incident I could clearly see that must have been a stressful time.
Playing the role of a caregiver needs a huge spec of qualities Which you have mentioned....
The most important quality I consider timid is patience. There re some situations where the person whom the care is given to, duevtibyhe ailments decides to develop habits or behavior Which may annoy the caregiver. Other qualities are well explained which with love and a good communication skill being a caregiver will become less task full.

What goes around comes around

Thanks for sharing and good luck with the challenge...
