"Surely the me of tomorrow will be more emotionally competent to handle this burden than the me of right now."

It isn't that. It is just "working on this makes me feel bad, so I will avoid doing it." There isn't an expectation that tomorrow it will be easier. I just want to work on a different thing that doesn't make me feel bad right now.

Where for me, "feels bad" starts at the body getting tensed up and the gut being twisted, and goes up from this to becoming nearly paralyzed and tortured, with higher cognitive functions shutting down and even the simplest incremental action on the task requires forcing my own limbs to move.

It's like the physically painful stress of suddenly having to make a very difficult choice, except it doesn't go away until I finish the task, give up on it, or... just do something else. So it's less of a "I will avoid doing it", and more of the mind giving up under torture.

This heavily contributes to what I've heard as the Adversity Paradox: we don't like adversity, but find meaning in the overcoming of it.

Unfortunately, from my own experience, my feelings of inadequacy and unease about what I can't know constantly cloud my higher-order reasoning.

Bad thinking is also, tragically, habit-forming.
