junie1 you must be devastated. I am so sorry you feel alone at a time when you really need loved ones around.
Others have made suggestions so I will add to take things slowly and be very easy on yourself.
I found the Sue Ryder on-line bereavement site very helpful when someone close to me died.
Please keep posting here if you feel the need- you will get good advice and support from people who know how it feels.
Don't be frightened to contact old friends and colleagues your husband knew too. They may be more supportive than you think.
