When rejection feels like an emergency for neurodivergent people

As both a therapist and a parent of a neurodivergent child, I often find that the topics I explore professionally are the same ones showing up around my kitchen table. Over the past year, I’ve been exploring two concepts that frequently appear in conversations with neurodivergent adults and parents of neurodivergent children: limerence and rejection-sensitive dysphoria (RSD).

I initially started exploring these ideas through my curiosity about emotional regulation and attachment within neurodivergent families and communities. But the deeper I looked, the more I realised these experiences are widely discussed within neurodivergent spaces, yet still relatively misunderstood in mainstream mental health conversations.

Many people describe these experiences as overwhelming, confusing and sometimes deeply distressing. Understanding how they connect can help bring clarity to reactions that might otherwise feel "too big", irrational, or shameful.

What is rejection-sensitive dysphoria (RSD)?

Rejection-sensitive dysphoria is a term commonly used in neurodivergent communities, particularly among autistic people and those with ADHD. It describes an extreme emotional response to perceived rejection, criticism or disapproval.

The keyword here is perceived. Even small social cues – a delayed reply to a message, a change in tone, someone appearing distracted – can trigger a powerful internal reaction.

People often describe the experience as:

• sudden emotional overwhelm
• intense shame or panic
• feeling certain they have done something wrong
• a strong urge to repair, withdraw or escape the situation

It can feel less like disappointment and more like an emotional alarm system going off in the body. For neurodivergent individuals who may already find social cues difficult to interpret, this heightened sensitivity can make relationships feel unpredictable and unsafe.

What is limerence?

Limerence is a term originally coined by psychologist Dorothy Tennov to describe an intense form of emotional infatuation or attachment.

While it is often discussed in the context of romantic relationships, limerence does not have to be romantic. At its core, limerence describes a pattern of intense emotional focus and longing for connection with a specific person, which can occur in a variety of relational contexts, such as with a friend, colleague, mentor, therapist, or any person who feels emotionally significant or safe.

In children and young people, this attachment may centre around a friend, teacher, teaching assistant, coach, or another supportive adult in their environment.

Limerence typically involves:

• intrusive or repetitive thoughts about the person
• a strong desire for connection or emotional reciprocation
• emotional highs and lows depending on perceived signals from that person
• hyper-focus on interactions, messages, or perceived meaning

In limerence, the brain becomes highly attuned to cues of acceptance or rejection. A friendly message, smile, or positive interaction can create a strong emotional high. Conversely, distance, lack of response, or perceived disinterest can trigger intense anxiety or distress.

While limerence can occur for anyone, many autistic individuals and people with ADHD report experiencing these patterns more intensely or more frequently, particularly when the relationship provides a sense of safety, understanding, or belonging.

Where limerence and rejection sensitivity overlap

When limerence and rejection sensitivity intersect, the emotional experience can become particularly powerful. Both involve a heightened sensitivity to relational signals.

For someone experiencing rejection sensitivity, the possibility of rejection already feels threatening. When limerence is present, the emotional stakes around that specific person become even higher.

This can create a cycle that looks something like this:

1. strong emotional focus develops on one person
2. the brain begins scanning constantly for signs of acceptance or rejection
3. small signals are interpreted intensely
4. perceived rejection triggers a rejection sensitivity response
5. the emotional pain increases the focus on the relationship

Many neurodivergent people describe this as feeling like being on an emotional rollercoaster they cannot get off.

Linking limerence and rejection sensitivity in children and young people

In children and young people, limerence may not look like romantic infatuation. Instead, it often appears as an intense emotional attachment to a trusted adult or friend.

A child might become particularly focused on a teacher, teaching assistant, or mentor who makes them feel safe and understood. They may think about that person frequently, seek reassurance from them, or feel especially distressed if that person seems unavailable or distant.

When rejection sensitivity is also present, even small changes – a teacher being busy, speaking more sharply than usual, or giving attention to another pupil – can be interpreted as rejection.

The child’s reaction can appear disproportionate to the situation, but internally, it may feel overwhelming. What looks like a small moment to others can trigger a deep fear of losing a relationship that feels incredibly important.

Understanding this dynamic can help parents and professionals respond with curiosity and compassion, rather than assuming the child is simply being “overly attached” or dramatic.

Why might this be more common in neurodivergent people?

There are several possible reasons these experiences appear more frequently in neurodivergent communities. These include:

Pattern recognition and hyperfocus

Many autistic people and individuals with ADHD naturally engage in deep thinking and hyperfocus. When that focus turns towards a person or relationship, the brain can become highly invested in analysing every interaction.

A history of social rejection

Research shows that neurodivergent individuals often experience higher levels of bullying, exclusion, or misunderstanding growing up. Repeated social rejection can create a nervous system that becomes highly alert to relational threat.

Emotional intensity

Some neurodivergent people experience emotions very strongly. When attachment, connection, or belonging are involved, these emotions can feel overwhelming.

Difficulty interpreting social signals

If social cues are harder to read, the brain may fill in the gaps – sometimes assuming the worst.

When the body goes into alarm mode

Something important I often explain to clients is that reactions linked to rejection sensitivity are not simply “overreactions”. They are often nervous system responses.  When the brain interprets something as social danger, the body can move into fight, flight, freeze, or fawn responses.

That’s why someone might:

• send multiple messages trying to repair the situation
• withdraw completely
• feel intense panic or shame
• struggle to think clearly

In these moments, the body is trying to protect itself from perceived relational loss.

Supporting regulation before reasoning

One of the most helpful shifts can be recognising that logic rarely works while the nervous system is in alarm mode. Instead, regulation needs to come first. A common mantra in our house is: “We fix the body before we fix the problem.” When emotions surge, the body often enters a stress response. In this state, the thinking part of the brain is far less accessible.

Supporting the nervous system first might include:

• breathing or grounding exercises
• movement or sensory regulation
• stepping away from the situation briefly
• co-regulation with a calm adult
• gentle, compassionate reassurance

Once the body settles, the brain becomes far more able to reflect on what actually happened and consider alternative interpretations.

Trying to reason with someone while their nervous system is in full alarm mode is a little like trying to have a calm conversation during a fire alarm – the priority is to quiet the alarm first.

Moving from shame to understanding

Many neurodivergent adults describe feeling embarrassed or ashamed of these reactions, especially if they have been told they are “too intense” or “too sensitive”. But when we understand the interaction between rejection sensitivity, attachment, and neurodivergence, the picture becomes much clearer.

These responses are not character flaws. They are often the result of a nervous system that has learned to work very hard to protect connection and belonging. With awareness, regulation tools, and supportive relationships, people can learn to recognise these patterns and respond to them more gently.

A note for parents and carers

For parents and carers, recognising these patterns can also bring a sense of clarity. An intense attachment to a teacher, mentor, or friend may not simply be a “phase” or an attempt to gain attention. Often, it reflects a child finding someone who makes them feel safe, understood, or emotionally regulated.

When that connection feels threatened, the reaction can seem sudden or disproportionate. But through the lens of rejection sensitivity and attachment, these responses can begin to make more sense.

Responding with curiosity rather than criticism can help children learn that strong emotions are something that can be understood and supported, rather than something they need to hide or feel ashamed of.

As conversations about neurodiversity continue to grow, so too does our understanding of the emotional experiences that can accompany it. Exploring concepts like limerence and rejection sensitivity can help many people realise they are not alone in reactions that once felt confusing or overwhelming.

For parents, it can offer a different lens through which to understand a child’s intense attachments or emotional responses. For neurodivergent adults, it can provide language for experiences that may have felt deeply personal or isolating.

Sometimes, simply having words for what is happening internally can be the first step toward greater self-compassion. And when we begin to understand the nervous system processes behind these experiences, what once felt like a personal failing can start to look more like an emotional alarm system that has learned to ring very loudly in order to protect connection.

With awareness, compassion, and the right support, that alarm can gradually become easier to recognise, regulate, and respond to.
