I was starting to think emotional flooding was happening to me more often. Then I realized — it wasn’t happening more. I was finally recognizing it when it did.
I’m Brett, the AuDHD Boss — a late-diagnosed AuDHD (autism + ADHD) person with over 12 years in corporate leadership. On this site and on YouTube, I write and talk about what it actually looks and feels like to be neurodivergent in the workplace.
Emotional flooding is a state of emotional overwhelm where the nervous system becomes so activated that normal processing shuts down. For AuDHD and ADHD brains, it tends to hit harder and last longer — because everything, past and present, arrives at once.
What Is Emotional Flooding?
Emotional flooding is what happens when a trigger hits and your nervous system decides there’s a threat. Not always a dramatic one. Sometimes it’s a misunderstanding in a meeting. A message that reads wrong. Someone responding with frustration when you thought everything was fine.
For me, one of the biggest triggers is being misunderstood — especially after I’ve worked hard to communicate clearly. When someone takes what I’ve said and runs with it in the wrong direction, something in my body just trips.
What Emotional Flooding Actually Feels Like From the Inside
The ADHD part of my brain starts firing questions in every direction at once. How did we get here? What did I miss? Did I say something wrong? What’s the context I’m not seeing?
At the same time, my body is already in full anxiety response — heart rate up, breathing heavier, that coursing feeling of stress moving through my chest and arms. I need to move. I need to get up and walk. But I’m still in the meeting, or still staring at the email, still trying to hold it together.
And I’m masking. Even while I’m flooded — thoughts crashing, body activated, brain trying to process fifteen things at once — I’m still trying not to let any of it show. Which means I’m burning energy I don’t have to appear calm when I’m anything but. Sometimes it leaks out anyway as defensiveness, a slightly sharper tone, a question that comes out wrong.
Why AuDHD Brains Get Hit Harder
Flooding is harder for AuDHD and ADHD brains than it might be for others because we can’t easily file experiences into separate buckets while it’s happening. Everything comes at us at once — current emotions, old memories, past conflicts that feel suddenly relevant, sometimes trauma that has nothing to do with what’s happening right now.
The nervous system doesn’t always know the difference between then and now. A sharp email in 2025 can feel connected to a situation from ten years ago, and both land with the same weight at the same moment.
What Happens After the Flood
Once the immediate situation is over, the work isn’t done. I pace. I reread the message. I spiral on it. I need a safe person — someone I can verbally process with, someone who can help me figure out what actually happened and help me come back down enough to think clearly. Only then can I start completing the stress cycle: moving my body, drinking water, talking it out, letting my nervous system know the threat has passed.
And then I crash. Every time. Brain empty, body depleted, sometimes unable to take in anything new for hours. That’s the real cost — not just the emotional flood itself, but the recovery. If it happens in the middle of a workday, the rest of that day is often just gone.
What Managers Need to Know About Emotional Flooding at Work
You don’t need to know someone’s specific triggers or their full history to reduce the chances of this happening on your team. It’s not your job as a manager to fix anyone. But how you deliver difficult information matters.
Manage expectations before hard conversations
How you set up a call or write an email before a difficult conversation matters. Whether you give someone a heads up — “hey, I want to talk through something with you later today, nothing serious or urgent, just want to make sure we’re aligned” — versus dropping something on them with no preparation makes an enormous difference to someone whose nervous system is always scanning for threat.
Four things that actually help:
- Lead with curiosity
- Give context before conclusions
- Assume positive intent before assuming negative
- Ask questions before drawing conclusions
These aren’t just communication best practices. For the people on your team who are carrying things you can’t see — and most of us are — they’re the difference between a productive afternoon and a recovery afternoon.
Choosing words carefully isn’t about walking on eggshells. It’s about recognizing that everyone brings their full self to work, whether anyone can see it or not.
Frequently Asked Questions About Emotional Flooding and AuDHD
What is emotional flooding? Emotional flooding is a state of emotional overwhelm where the nervous system becomes so activated that normal processing shuts down. For AuDHD and ADHD brains, it tends to hit harder and last longer — because everything, past and present, arrives at once.
What triggers emotional flooding in AuDHD people? It can come from conflict, a misunderstanding, or something that seems minor on the surface. For me, one of the most consistent triggers is being misunderstood — especially after working hard to communicate clearly. When someone responds with frustration or takes something I’ve said in the wrong direction, my nervous system reads that as a threat, even if the rational part of my brain knows it’s not a crisis.
What does emotional flooding feel like physically? Heart rate goes up, breathing gets heavier, and there’s a coursing feeling of anxiety through the chest and arms. The need to move — to get up and walk — becomes urgent. At the same time the brain is firing questions in every direction and trying to process everything at once. It can feel like an anxiety attack because in many ways it is one.
Why is emotional flooding harder for AuDHD brains? Neurotypical brains can generally filter and sort emotions as they arrive. AuDHD and ADHD brains experience everything at once on a regular day — so when a flood hits, it brings current emotions, old memories, past conflicts, and sometimes unrelated trauma all at the same moment. The nervous system doesn’t always distinguish between then and now.
How do you recover from emotional flooding? Recovery requires completing the stress cycle — physically moving, drinking water, talking it out with a safe person. For me that means getting away from whatever triggered it, not responding to anyone until I’ve processed, and verbal processing with someone I trust. Even after the flooding stops, the brain and body are depleted. It can take the rest of a workday to fully come back.
Can emotional flooding happen at work even if nothing “big” happened? Yes. A single email written with the wrong tone, a meeting that goes sideways, a message with no context attached — any of these can set it off. The trigger doesn’t have to match the intensity of the response. That’s part of what makes it so hard to explain to people who haven’t experienced it.
What can managers do to prevent emotional flooding on their teams? You don’t need to know someone’s specific triggers or history. Leading with context, giving a heads up before difficult conversations, assuming positive intent, and asking questions before drawing conclusions can significantly reduce the chances of triggering a flooding response in neurodivergent employees — and honestly, in anyone.
This post was partly inspired by Bridget Manstead, a neurodivergent social justice writer on Substack, whose recent post on a similar experience resonated deeply. I’ll also be talking more about flooding and neurodivergent relationships with Caroline McGuire, author of Friendship Skills for Neurodivergent Adults (available for pre-order now), in an upcoming episode — stay tuned.
