Yes, precious that you have him by your side.
I've been in that intense emotional, fearful place, very unpleasant, managed to get through (surgery, hospital stay some 8 y ago).
Yesterday I felt a bit wonky, dehydrated, sun pressed, sugar lowered by the end of the walk with Dad...and I was scared , to whom do I let him and fetch help for me?
Whom do I call? Boyfriend is at work, so I consoled myself I can ask passers by, if it gets critical.
We succeeded, but I felt the remnants of fear until 4 pm.
It's more or less fine now.
But for years, the last 4 years I felt my stomach cramp every time I needed to assist my parents. Sometimes more, sometimes less. It wears one out.
Breathing ( box breathing) and prayers are what get me out. And of course, snacks and hydration, hat...shade...rest...
No way out, only through.
Proud of you, you made it!
