Once again, thank you all for the very kind and helpful words 
@PamfromCT Wake, funeral mass and burial is exactly what I have always experienced. My mothers' will stated she didn't want a wake (perhaps because she chose cremation) but did want the funeral mass and burial service with a reception to follow at a specific restaurant (funds put aside to cover that cost as well).
I believe what is making this more difficult is that she died alone at the hospital (I was not allowed in ; no visitors in any way no matter the circumstance) and I don't believe she was giving the last Sacrament due to the speed of her death. Her faith was very important to her and knowing what she wanted...all of this is weighing very heavily on my heart
I simply want to do the right thing by her just as I did for my father many years ago.
I called the Rectory this morning and left a message for her priest. I'll go from there.
