When Emotions Run High, Why Is It So Hard to Communicate?

What happens to listening, thinking and responding when we become overwhelmed

You start a conversation intending to sort something out.

Ten minutes later, you're talking faster, repeating yourself and becoming increasingly frustrated that the other person still doesn't understand.

Or perhaps you have the opposite experience.

Your mind goes blank. You know you have something to say, but you can't find the words. The more questions you're asked, the harder it becomes to answer.

Later, when things have settled, you know exactly what you wish you'd said.

So why can something that seems perfectly clear afterwards become so difficult in the moment?

When we're overwhelmed, we don't communicate in the same way

Strong emotions aren't inherently a problem.

Anger can tell us something feels unfair. Hurt can show us that something matters. Anxiety can alert us to uncertainty or threat.

But as the intensity builds, it can become harder to listen properly, take in new information, consider another perspective or work out what we actually want to say.

Research with couples has described emotional flooding - becoming so overwhelmed during an interaction that it becomes difficult to engage with the conversation as we normally might.

This can create a frustrating experience many people recognise:

I knew I wasn't handling it well, but I couldn't seem to do anything differently.

Overwhelm doesn't look the same in everyone

Some people become more expressive when they're upset.

They talk more. Their voice gets louder. They repeat themselves, interrupt or become increasingly focused on getting a response.

Others become less expressive.

They get quieter. Look away. Give shorter answers. Struggle to find words or want to leave.

Research into emotion regulation during couple conflict has found similar differences in the ways people respond when emotions become intense.

But what we see on the outside doesn't necessarily tell us what's happening underneath.

The person talking loudly may be hurt or frightened underneath the anger.

The person who has gone quiet may be experiencing just as much internally.

We respond to what we can see, but what we can see isn't always the whole story.

We affect each other

Imagine you're already upset and your partner rolls their eyes.

Or you're struggling to find your words and they say:

“See? You never have anything to say.”

You're unlikely to become less upset.

The opposite happens too.

Someone slows down. Their voice softens. They stop preparing their defence and actually listen.

The conversation starts to feel different.

We don't regulate our emotions completely independently of the people around us. In close relationships, we affect each other.

This doesn't mean another person is responsible for regulating our emotions for us. But their response can make a difficult moment easier or harder to manage.

Sometimes the more upset we get, the more urgently we want to fix it

When something feels threatening to an important relationship, leaving it unresolved can become increasingly difficult.

We might start thinking:

I need them to understand.

We can't leave it like this.

Why won't they answer me?

So we keep going.

We explain ourselves again. Ask another question. Try one more time to make the other person understand.

The more distressed we become, the more urgent the conversation can feel.

And that's the trap.

Trying harder to resolve something while we're highly upset doesn't necessarily help us resolve it.

Sometimes the conversation needs less intensity before it needs more words.

Notice your early signs

It's much easier to do something differently at a six out of ten than a ten.

The trouble is that many of us recognise overwhelm much more easily afterwards.

Think about what happens to you before a conversation really starts going off track.

Maybe your jaw tightens.

You start interrupting.

You stop listening and begin rehearsing what you're going to say next.

You make the same point again because surely if you explain it one more time, they'll understand.

Everything starts sounding like criticism.

Or you go the other way.

Your mind becomes foggy. You stop taking much in. Finding words gets harder and all you want is out of the conversation.

Your signs will be your own.

The useful question is:

What happens to me just before I stop communicating well?

Recognising that point gives you more chance to do something with it.

Sometimes a pause is useful

Recognising overwhelm doesn't mean every difficult conversation should stop.

There are things we need to talk about even when they're uncomfortable.

But there are also times when continuing isn't getting either person anywhere.

Saying:

“I'm too worked up to talk about this properly. I want to come back to it. Can we have half an hour?”

is very different from walking away without explanation.

The problem hasn't disappeared. You're recognising that you're no longer in a good position to deal with it.

What happens during the break matters too.

If you spend the whole time replaying the argument and preparing your next response, you may return just as worked up as when you left.

Sometimes you need to do something that actually helps you settle enough to think and listen again.

Regulation isn't the same as getting rid of the feeling

Being emotionally regulated doesn't mean being perfectly calm.

You can still be angry.

You can still be hurt.

You can cry, need reassurance or tell someone that what happened wasn't okay.

The aim isn't to make ourselves emotionally neutral before we're allowed to have a difficult conversation.

It's having enough room around what we're feeling to make some choices about what happens next.

Can I hear what the other person is saying?

Can I explain what happened for me?

Am I making assumptions about what they mean?

Can I disagree without trying to hurt them?

Do I need some time before I can do any of those things?

Those questions are much more useful than telling ourselves: I shouldn't feel this upset.

The conversation might look different later

Once things settle, we sometimes understand our reaction differently.

I wasn't just angry. I felt embarrassed.

I kept pushing because I was worried you didn't care.

I went quiet because I felt criticised and couldn't think of anything that wouldn't make things worse.

That doesn't undo what happened, but it gives us something more useful to bring back to the conversation.

You might say:

“I know I got defensive before. I think I felt criticised and stopped listening.”

Or:

“I kept pushing for an answer. I think I was getting more anxious the longer we left it unresolved.”

We will all get overwhelmed sometimes. What helps is learning to recognise our own signs a little earlier, before the conversation gets away from us.
