You and your problems are real, and they do matter. You're allowed to care about yourself and your family. (You aren't interrupting a discussion of the current events in Christchurch or Madison to say "that's interesting, but I need to get a new dryer" or "never mind those foreigners, what about my grandfather?")

Nor will anyone in Libya or New Zealand be helped if you sit worrying about them instead of about your family and your mental health. Think about them, yes. Think about what, if anything, you are going to do to help. Then do it, and go on to the next thing. You aren't an EMT in New Zealand, there's nothing useful you could accomplish by dropping your own life right now.
