You're at the grocery store. You are standing perfectly still, reading a label on a jar of pasta sauce. Suddenly, someone aggressively pushes past you to grab something on the shelf, thumping your shoulder hard.
Before you even process what happened, you instinctively blurt out: "Oh, I'm so sorry!"
They don't even look at you. They keep walking. You stand there, your heart racing, feeling intensely foolish. Why did you apologize? You were standing still. They hit you. You did absolutely nothing wrong. Yet, the phrase "I'm sorry" bypassed your conscious thought and flew out of your mouth like an emergency reflex.
This is not politeness. This is an ADHD survival tactic.
Living with untreated ADHD means spending your formative years in a constant state of 'falling short.' You forgot your homework. You lost your keys. You interrupted a teacher. You disappointed your parents. Every single day, your neurobiology actively caused micro-crises for the people around you. You quickly learned that the fastest way to de-escalate their justified anger was to immediately accept the blame and lower your status.
Now, your brain runs this script by default. The amygdala interprets any sudden environmental shift or minor friction as a massive social threat. Saying "I'm sorry" is your neurochemical panic button. It is a desperate attempt to perform 'Emotional De-escalation' to protect yourself from the excruciating physical pain of RSD.
