@aggroed, I am sorry for your loss, I had the wind knocked out of me last week as well, when i found out a very good friend of mine was found lying on his floor, no one is quite sure what happened yet.
The way you grieve the passing of your loved ones, is personal to you and whatever way you choose to do that is your prerogative. In actuality I think its a great way to have some alone time to console yourself.
my thoughts are with you at this time. All the time and effort you spend helping us all out is much appreciated. Stay Strong!!
