That's a normal part of the process of grieving. But speaking as a parent, as much as I hate knowing that my children will mourn for me one day, that is far better than my outliving them. I'm not sure I could bear it. I nearly lost my daughter a year and a half ago, and I'm still reeling from that.
I really like that Random City Map generator and the blue print generators. I always enjoy stuff like that.

I'm glad this thread has been brought back from the dead, zombie style, and I hope people start dropping off ideas here again. Especially since I'm crap at coming up with my own!
