Oh C Ann, how horrible, I am so sorry.
I can echo the 'funeral director" will really be helpful. You will need to decide where to have the 'wake', at her home or at a church or a local restaurant. You will have tons of people asking how they can help.
Take them up on it, that is what friends and loved ones are for!!! Don't be shy, ask them for
specific things (can you grab coffee, styro foam cups, tissues, soda.. for the house?) Can you take out the garbage on saturday, we might forget?... Can you bring over left-overs containers for the food (she will probably be overwhelmed with food contributions) Can you clean out the frige to make room? I know these things seem small and weird even, but you will both be VERY overwhelmed in the next few days, every bit of help is going to lessen some of the anxiety. It will be very difficult for her to make even the smallest decision. Make the tiny ones for her.
You will need to decide who will be pall bearers. You will need to decide what he will be buried in, and if she wants him laid out with his wedding band and buried with, if there is something special you want to place in his pocket? Gosh, these are really hard questions, but they will be all asked right away by the funeral director. Call
her doctor and tell them what she is dealing with, she will be so out of it , she may forget what is necessary to take care of her own health. If she has health issues, it is a good idea for her doctor to be aware of her situation. He may want to prescribe something to help ease her anxiety for the next few days.
Remember to take care of yourself as well, to keep drinking fluids and eat even if it is just a bit here and there (sounds dumb, but if you dehydrate youself, you will end up passing out...it happened at my fathers funeral to my sister)
I will keep you in my prayers....how sad...HUGS
