Basically her body is owned medically and a victim of Medicare.
YES, she could recover, but 99% will never try, they love their medicare, free drugs and medical attention and they have lived their lives trusting medical and not nature.
The odds are against you! I personally have never seen a diabetic who is on insulin ever take the first step towards living, they are to preoccupied with dieing.
I suggest you read what I call BOOK I, it suggest that the O/J fast was a cure for all. Dr. Christopher suggets that the Pancreas Balance taken daily can reduce and eliminate the need for insulin, etc.. he also suggest herbs can repair the heart. The O/J fast stakes as medical fact that you receive a brandnew heart in 21 days, etc...so what I am really suggesting is to study these 2 authors and then see what mom has interest in.
My experience has been this:
We came into the world as one and we leave as one, we answer to God as One. Our parents do as they please and they answer to God, while we can learn from our Parents mistakes and not do as they did.
Love and Herbs go along way in health, if you can care for your mom daily and she is not a heard head as many people on drugs and 70 are, you may have a chance, but otherwise many of these old people will blame the herbs for their problems and only trust ther expensive drugs. They call herbs old fashioned.
The dieing person has lost their Spiriual connection and the spirits within them LOVE DRUGS, they LOVE to torture the body God Created.....Many drugs will allow you to experience these spirits, when the elderly person is irritated the spirits will show them self and if you confront them they may warn you that if you don't back off, you just may be the next one to die in the family, etc....this is why I suggest we all take care of our selves, because the day we can't, is the day we are screwed.
Parasites/Spirits hungerly await for our Immune System to fail under the load of accumulated waste/metals; then its supper time for them. They will torment the human body till death.
