Hello Jayne: I see this is still just your third post here on PC. So... welcome to Psych Central.

My condolences on your loss.

Shouldering all of the responsibilities you now have must be extremely difficult for you. Hopefully being here on PC can be of at least some comfort & support.
Here's a link to DocJohn's article on grief & loss from Psych Central's archives. The article also provides links to additional articles on the subject:
