Hi and welcome, I hope this forum will give you a little comfort.
I agree with Norma, the best councillor is right by your side, obviously I don't know your husband, but talk to him, you might be pleasantly surprised. My wife and I had a very close relationship, I could talk to her about anything and I like to think she could with me too, I realise of course, that sadly some relationships are not the same.
The loss of my own father had a great affect on me too, I still miss him today, losing someone close to us affects people very differently. Some members of my family seem to be able to shun it off quickly, once the funeral is over, it's as though that person who's funeral they attended had not even existed, while some of us, the memories, and love we felt for them stays with us all our lives.
