@formydad The medical community has a lot on their plates, and sometimes forgets the human element. Many times in the past, when faced with a "professional" who wasn't, or given a choice that I could not easily decide, I will ask that person, "Is that how you would like your family member to be treated?" or, "If I was your favorite cousin, what would you advise given the information we have?" There are times it draws them up short and has them reconsider their approach.
It's okay to be frustrated, and angry, and sorrowful. Most all of us here have been in those same shoes at least once. We are all here to offer support and the lessons we have learned from our own experiences.
Get better soon from that stomach bug! Give your folks a big hug when you see them next, and Happy New Year to you and yours, also.

@formydad I’m so glad that your dad is home. You mentioned that he will give himself antibiotic shots. This is frequently done by a home care nurse. Did the hospital discuss this with you or your parents?
And remember that infection control is extremely important! What information have your parents been given on infection control?
