Two people I've loved have committed suicide.  I'm still pissed at them for doing it, but I realize that they were both very depressed people.  Depression can kill.  It can cause suicide and/or homicide and needs to be taken care of.  

Logically, I can understand why these two people felt the way they did, but that does not mean there really was a good reason they had to do it.  Things change. The situation that caused them to do what they did would change, but they'll never see that now. Sigh. Suicide is incredibly sad, yet maddening when it happens. The people left behind have to deal with picking up afterwards.

I can understand when someone is terminally ill and wants to hurry the inevitable. Fine, they should be able to do it in an open manner and give everyone a chance to say goodbye. I'm all for that. Leave the survivors behind with a heavy heart, but not a heavy mind.
