This is a hard thing to say, but faith healers really don't work.

There is someevidence, that the beliefs of the sick person can make a difference.

However there is no evidence of a magic faith healing wand - and there have been many studies.

Lots of people will disagree with me, and possibly question the nature of scientific research on such things. I do however think that this is a case of 'wanting to believe' very badly, and making 2+2=5

I wish you and your mother well, but as CarolC says, a hospice, and trying to get some emotional peace might be a better strategy.

Not what you wanted to hear, I know.

Love and tranquility to all your family
