So sad to read that your husband has died, my deepest sympathy Marmalade.
I do hope that his peaceful passing manages to give you some comfort. It did me later after the initial shock of the suddenness. He had suffered for months with non-top chest and urine infections. But I was comforted that the end was peaceful as it could have been very different. It is as you say, a peaceful release.
I wish you the strength needed to do all required at this time. Remember we are all here for you so don't be a stranger.
Look after yourself, it wont be easy and grief can make you feel so tired.
Thinking of you and sending love
