I am so very sorry about your husband....This is something very hard to experience and watch.
Hospice groups generally are very helpful in helping you navigate through this trauma. My husband's wishes were to be at home, but I am a nurse and was able to care for him. In fact had to ask the Hospice nurse to please leave the house when she came. She wanted a family member to go pick up his pain medication as he was actively dying! Why one would do that I have no idea.....not a fan of Hospice services anyway for many reasons.
