I think caring about people the closest to you can be the hardest. I love being a nurse and caring for others who are sick comes easily. I remember one time I was really frustrated with a difficult patient, just real done with them and a fellow nurse reminded me that I get to go home at night and they didn't. It made me see things different. But with people in your extended family, that's harder to just leave it at work or the family closet with all the skeletons ?....just saying.
Once you put some distance between you and them so you can get a handle on becoming too involved, then it seems like you don't have a relationship with them at all. So here's to trying to care without getting too involved. If that is even possible.
