I am at peace with what is happening and what will happen.

Peace with the future can't be built out of prediction. You don't have the information and never will.

What it can be built out of is your own record. Not a record of good outcomes — plenty of them were bad — but of having been present for every single one.

Every worst day so far has been survived by you. Not gracefully. Some were got through badly, with help, with weeks afterwards spent recovering and a fair amount of it forgotten on purpose.

It is still a complete record. Whatever is coming will meet somebody who has done this before.
