The prayer below is a Jewish prayer that I just found. I am not Jewish but I believe the prayer fits your circumstance. I thought it was an unusual prayer. I like it and I hope it provides you with strength to carry on.

Prayer for Good Health

Blessed are You, the Lord our God,
King of the Universe,
Who fashioned man with wisdom
And created within him many openings and cavities.

It is obvious and known before Your Throne of Glory
That if but one of them were to be ruptured,
Or but one of them were to be blocked
It would be impossible to survive and stand before You.

In the merit of my appreciation for Your wondrous works,
May You grant me good health and long life.

Best regards and Sweet Dreams, wolf
