Hello Dee,,and welcome.
First of all I do offer you my sincere condolences for your very sad loss.
It's still such very early days for you, and of course it's perfectly natural to feel the way you do getting angry, as it's all part of the bereavement process and coming to terms with the shock of the suddenness of loosing him.
You'll find it will help tremendously to unload all the pent up emotions going on inside you at the moment just letting go of them here, and not bottling them up for fear of hurting loved ones around you missing him too.
The pain you are in which will seem unbearable at times I know, I promise you will ease as healing time goes by, but right now just don't push yourself taking baby steps each day until you get a little stronger.
Take care. Dave
