Tza'ar

This past week was a tough one. My friend's mother had passed away after batteling with cancer for several years and another friend of mine's husband had surgery to replace one of his heart valves after discovering he had a severe heart murmor. There are so many targic things that I've been hearing about and I wonder was the world always filled with these things? Or are we now only finding out about them, whereas in our childhood we were constantly protected from them? I don't know the answer but all this is a little too much for one's plate. I only daven that Hashem bring them comfort and that we should only hear besoros tovos.
