It really pains me just by reading through your post kuya @adamada ... and I cant really imagine how I would feel beeing on your position to see someone and look them in the eyes and know that they need help but theres just thing that we can't control in life...
Man, what a story you shared this time...
You get used to it. This is why people that worked long in health care, especially those that have been in it for years learned how to move without thinking much about things beyond their control. There's nothing I could do if the folks or patients themselves gave up too so better focus on those cases that can still change their fate.
