Most of the time, when dealing with grief, it's far too personal to try to imbibe it with one's own perspective. I didn't want to imply that you were grieving incorrectly or that you should do things differently. As long as you don't let it fester (I think that's where people have issues, when they become trapped in the emotion, as I've done before) I know that grief is good for the soul.
@uniwhisp is absolutely right when she says that it's not bad. Btw, I love the word catharsis, it reminds me of cathedral, and it's an awesome word. +1 to you.
