I'm sorry for your loss. I haven't been on NES much since October, just lurking occasionally.
Three days after your Father died, my Daughter died suddenly. I had a post in draft the hours before she died in the "My Daughter wants to Shoot" Thread, so that's where put it. I was kind of out of it. My wife and I have been going to a Grief Therapy Group. In my experience it's getting easier, not necessarily better. Time seems to dull the raw nerve. Thanksgiving and Christmas were rough. May God grant you Serenity.
