See the last two suggestions in my post.Also books on Emunah.
When my mother was very sick and people were calling us kids with this cure and that cure,we didn’t know what to try first,etc.
My life changed when I received Chovos Halevovos in English RANDOMLY in the mail one day.
I opened up RANDOMLY to a page which said Hashem once used a POISONOUS BRANCH to make the waters of a bitter river sweet…from which we learn that even a “mistakenly chosen” cure can bring about an actual refuah–if Hashem wills it to be.
As long as a person is making carefully considered choices,he can be zoche TO A COMPLETE REFUAH.
