Man that's a rough period for you. I've gone through similar, the deaths tend to cluster. My dad was a pretty weird guy but he had some interesting insights, and one of them was "the only real sign that you get older is how often you have to wear black, and then one day they'll be wearing black for you, but don't let it get you down, it is the reason to live as if it really matters". At 9 I didn't really know what to do with that information but now that I'm 57 it rings quite true.

Hang in there!
