Hi,
You said “Instability is a part of life in this universe that’s not within anyone’s control and this is the nature of this world.”
I’m not at the height of helping you (perhaps Lal) so what follows it’s just a little comment to your post : my actual insight is that the less anatta one becomes, the better one deals with/manages anicca (which understands the “instability”) and the less one gets into dukkha.
Your quest is so touching.
