Keep in mind that a natural death would not take into account your readiness. This is how most non-suicidal people die. Cancer or other medical conditions, car accident, pretty much anything other than living a full rich life and laying down comfortably at 100 years of age surrounded by loving family wishing you bon voyage.
My focus is trying to get practically ready. I am working on pre-paying funerary service, arranging all my stuff and so on to minimize any impact on others like family. Working towards setting it up so to others it will make no difference at all. It already does not make a difference, emotionally speaking, other than the relief to those that don't have to witness my disgusting presence (they are not expecting to witness a grotesque scum though and shouldn't be expected to witness one, so sparing them won't really be noticed). But moreso that when I'm gone it will only create joy and no inconvenience.
It is tough because the body still has to be disposed and all that.
I think getting everything ready still helps. Like having your method ready will give you peace to decide when, and knowing that anytime is as good as any. Could be as simple in my case as having a big metal drum to burn my last possessions and a bunch of thick shower curtains and shotgun ready to exit as 'cleanly' as possible.
But as far as the right time, your brain will ALWAYS find an excuse. Nature does not care if you watched all the latest skibidi toilet episodes etc. It does not care about your cliffhangers. Only you.
It's why I think free and open access to euthanasia would bring so much peace to people, not just the suicidal but those around them as we'd all be zenned out and just focused on working out the last good acts instead of in a state of intense anxiety and panic making more of a mess of our 'lives' and staving off the inevitable with drugs, entertainment, messes, bothering others socially even though we are not socially worthy etc.
In your specific case, with a pending move and wanting to make sure your spouse is taken care of situation...Nobody can tell you exactly when but I think you are thinking of the right things!
There will never be an ideal or perfect set of circumstances you can make happen.
But when you figure out what is optimal in terms of whether before the move, after the move but few memories, or forming a few memories first--you'll feel so much better if you dive deep in yourself and also observe others around you to feel more confident about what is best for them. Once you feel you know the best you CAN do, you will feel more at peace with the timing.
