I cannot do X, something I know I should do, because I do not have Y.
Well then how do you get Y? Or how else can you get to the goal of X.
I recently had a job candidate share that they couldn’t dress professionally because they are limited by the clothes in their closet.
Okay, but now what? You could let the employer know that you will expand your wardrobe if you get the job, that would go far. You could visit somewhere that donates clothes and ask for one professional outfit. You could spend an amount approximately equal to 2 of the coffees that you purchased before your interview to buy something slightly more professional.
Getting past your fist barrier is often doable, and it just might pay off to get you closer to your goals.
