There's a lot of crossover with ADHD and misophonia, which this is and OP may not know there's a word for it.

It's usually a VERY strong emotional response to certain noises, my main one is eating noises. It's an adrenaline fueled flight-or-fight response that makes me want to cry, scream, flip my desk, punch a hole thru a wall, etc. Most people filter out clicking pens or loud eating as "annoying" and move on but with misophonia it registers in your brain as DANGER and it becomes the only thing you can focus on. It can be managed but not controlled, it's extremely frustrating.
