Who do you have in your life who is really there for you, no matter what? Whether it be family, friends, etc -- who can you call at 3am, who would drop everything to visit or even stay with you in the hospital, who loves you unconditionally and really really cares what happens to you?
I've been thinking about my parents' health recently and have realized they might be the only people who really fill all of the above for me besides DH. I have close friends, but they all have their own families and their own busy lives. Besides spouses, are family (parents, siblings) usually the only ones who would fit all of the above for most people? (My siblings don't.)
