Be aware: You don't properly mourn the death of the first parent to die until the other one does as well.
My father died less than a year after my mother did, and it was far worse even though I was arguably closer to her.
I know this is not a particularly good time to be warning you about this but I wish somebody'd warned me and I probably won't get another reminder to do so. So, um, sorry, but I hope I'm right that it was worth saying.
