I feel you man. I was on my career break when I needed to be a nurse to my granduncle. Changing bandage twice a day, insulin, cook diet food, hospital appointment every 2 days etc.

Those things are not tiring but we are tired because of attitude ie. stubborn.

Good thing now we have a helper, otherwise I think I am going to die before anyone else.

Now I get why sometimes caregivers are the one who left the world first than those are sick. The stress level is nothing like work.
