People who are faced with a present situation that strongly points to an unbearable future -- like a cleric abandoned by his god to die on an alien planet and then go to Hell, say -- have several options for fleeing painful reality.
Consider the example of someone whose doctor has recently surprised him with with news that he has Stage 4 cancer, which is going to require painful and debilitating treatments; this will give him a small chance of surviving, but mostly he'll likely die gruesomely though a bit later.
One thing you could do, faced with this situation, is blind yourself to the Future's existence; you are just going to endlessly rehearse over and over how your current medical condition seems great, and you haven't seen it get worse, and probably the doctor is just wrong about that horrible stuff scheduled to happen to you later.
But this isn't a stable mental state at WIS 22, even without a dath ilani education. Cheliax does manage to teach you pretty thoroughly that the horrible painful Future you tried to ignore, will in fact show up later and hurt you.
A converse way out is avoid thinking about those present facts that point strongly toward awful things happening to you later, and find something you can be uncertain about, instead. If you are a mortal from a planet that can't scry afterlives, for example, you might convince yourself that Death is a very grand mystery and you can't possibly know what'll happen to you after that.
Over the last 48 hours, Esta's brain has settled on trying to dwell mainly on the question of how the Outer God's game might play out.
This occurred via the following cognitive execution pathway, which wasn't quite inevitable to the point where another mortal could advance-predict it happening to an arbitrary other person in Esta's situation, but which was nonetheless very common and ordinary in retrospect:
Most facts that Esta actually knows, point toward bad things happening to him.
Thinking about the actually-known facts is therefore painful.
The intentions of the Outer Gods, and the possible playout of their game, are things that Esta can tell himself that he doesn't know. He can manage to be radically uncertain about that.
Therefore, the least painful thoughts to rehearse and chew on endlessly are thoughts about the Outer Gods and the questionable purposes of Yog-Sothoth's game!
(Admittedly, in Creation this may actually be a valid source of hope, unlike other places whose inhabitants briefly try to take refuge in their uncertainty about superintelligent motivations. Outer Gods have mortal impacts that look more like they're being sampled from a distribution that significantly includes outcomes like "go around isekaiing people to other worlds", rather than being uncertain over a space of preferred outcomes more alien and hence more fatal than that.)
