Drowning in Doubt and Anxiety

I have a father with Stage 6 Alzheimer’s-living in a nursing home; a mother that has pancreatic cancer with 6-12 months of life left. My sister is less than a year from a massive heart attack, quadruple bypass, now a pacemaker and defibrillator.

How does ANYONE relax and feel better about this, when nobody can help when things get to the end? I’m drowning in doubt and anxiety….
