The amygdala in the ADHD brain is hyper-reactive to perceived social threats. Because of Rejection Sensitive Dysphoria (RSD), the brain does not distinguish between a polite, automated 'We went with another candidate' email and a direct, personal attack on your identity. Anticipating this rejection causes the brain to release cortisol before you even hit 'Submit.'
Simultaneously, the sheer volume of choices on a job board induces instant 'Decision Fatigue.' The prefrontal cortex must filter hundreds of chaotic variables (salary, location, title). Because the Working Memory buffer is so small, it cannot hold these variables simultaneously. The system crashes under the load.
Without an external "Gun to the head" (such as being fired or running completely out of money), the ADHD brain cannot synthesize the adrenaline required to override the cortisol freeze and the dopamine deficit. Thus, you wait in paralyzed agony until a true crisis forces you out.
