ADHD and Anxiety: Why They Often Overlap in Children and Adults (Lincoln, UK Guide)

ADHD and Anxiety: Why They Often Overlap in Children and Adults (Lincoln, UK Guide)

Many people who seek an ADHD assessment initially believe that anxiety is the main issue.

They may describe constant overthinking, emotional overwhelm, racing thoughts, difficulty relaxing, exhaustion, panic about everyday tasks, or a sense that life feels harder than it seems to for other people. Some have spent years trying to manage anxiety through coping strategies, self-help approaches, or therapy, only to feel that something still does not fully make sense.

For parents, the picture can be equally confusing. A child may appear worried, emotionally sensitive, perfectionistic, overwhelmed by school demands, or highly reactive under pressure. Teachers may notice difficulties with attention or organisation, while families see meltdowns, emotional exhaustion, avoidance, or distress around routines and transitions.

In many cases, ADHD and anxiety overlap.

At Profound Psychology, we regularly support children, adolescents, and adults across Lincoln who are exploring whether anxiety may actually be connected to underlying ADHD, or whether both are present together.

  • differences between ADHD and anxiety

  • emotional regulation and overwhelm

  • how anxiety develops alongside ADHD

What Is ADHD?

ADHD (Attention-Deficit/Hyperactivity Disorder) is a neurodevelopmental condition that affects:

  • attention regulation

  • impulse control

  • emotional regulation

  • executive functioning

  • activity levels

  • organisation and time management

Although many people still associate ADHD mainly with hyperactivity, ADHD can also involve:

  • internal restlessness

  • racing thoughts

  • emotional intensity

  • forgetfulness

  • overwhelm

  • difficulties starting or completing tasks

ADHD affects both children and adults and can present very differently from person to person.

Some individuals appear highly energetic and impulsive, while others seem quiet, anxious, distracted, or mentally overloaded.

What Is Anxiety?

Anxiety is a natural human response to stress or perceived threat. Everyone experiences anxiety at times, particularly during uncertainty, change, pressure, or challenging life situations.

However, anxiety becomes problematic when it is:

  • persistent

  • overwhelming

  • disproportionate

  • interfering with daily life

People with anxiety may experience:

  • excessive worry

  • physical tension

  • racing thoughts

  • panic

  • avoidance

  • sleep difficulties

  • emotional overwhelm

Anxiety can exist independently, but it is also very common alongside ADHD.

Why ADHD and Anxiety Often Overlap

The relationship between ADHD and anxiety is complex.

Some people have both ADHD and a separate anxiety disorder. Others develop anxiety as a consequence of living with undiagnosed or unsupported ADHD for many years.

Many individuals with ADHD spend significant amounts of time:

  • trying not to forget things

  • worrying about making mistakes

  • struggling to stay organised

  • feeling overwhelmed by responsibilities

  • trying to meet expectations despite executive functioning difficulties

Over time, this can create chronic stress.

A child who repeatedly forgets homework, loses belongings, struggles socially, or feels constantly behind may begin to feel anxious because everyday life feels unpredictable and difficult to manage.

An adult who misses deadlines, struggles with time management, feels overwhelmed by basic tasks, or constantly worries about underperforming may also develop significant anxiety.

At Profound Psychology, many clients describe feeling as though they are:

“always trying to catch up.”

This chronic sense of overwhelm can gradually contribute to anxiety symptoms.

How ADHD Can Look Like Anxiety

ADHD is frequently missed because many symptoms overlap with anxiety.

For example, someone with ADHD may appear:

  • restless

  • distracted

  • overwhelmed

  • emotionally reactive

  • unable to relax

  • forgetful

  • avoidant of tasks

These difficulties are often interpreted as anxiety without considering whether ADHD may be underlying them.

Racing Thoughts

People with ADHD often experience rapid, shifting thoughts.

This can feel very similar to anxious overthinking.

An individual may:

  • jump between thoughts constantly

  • struggle to “switch off” mentally

  • feel mentally busy all the time

  • become overwhelmed by competing demands

Because the mind feels constantly active, many people assume anxiety is the primary issue.

Avoidance and Procrastination

Avoidance is commonly associated with anxiety, but it is also extremely common in ADHD.

Someone with ADHD may avoid tasks because:

  • they feel overwhelmed

  • they do not know where to start

  • the task feels mentally exhausting

  • executive functioning difficulties make initiation difficult

Over time, this avoidance can create genuine anxiety because deadlines, responsibilities, and unfinished tasks accumulate.

Emotional Overwhelm

Emotional dysregulation is a major but often overlooked part of ADHD.

People with ADHD may:

  • react intensely to stress

  • feel overwhelmed quickly

  • struggle to regulate frustration

  • experience rejection sensitivity

This emotional intensity can easily be mistaken for anxiety alone.

Restlessness

ADHD-related restlessness is not always physical.

Many people experience:

  • internal restlessness

  • mental hyperactivity

  • difficulty relaxing

  • constant need for stimulation

Adults often describe feeling unable to fully “switch off,” even during rest.

ADHD Anxiety Symptoms in Children

Children with ADHD and anxiety may present in complex ways.

Parents often notice:

  • excessive worrying

  • emotional sensitivity

  • perfectionism

  • school avoidance

  • sleep difficulties

  • overwhelm with routines

  • emotional outbursts

  • fear of failure

At school, children may:

  • appear distracted or disengaged

  • avoid difficult tasks

  • become overwhelmed under pressure

  • struggle with organisation

  • seem inconsistent academically

In some children, anxiety develops because they are constantly trying to compensate for ADHD-related difficulties.

For example:

  • forgetting instructions may lead to fear of getting in trouble

  • struggling socially may create social anxiety

  • difficulties managing schoolwork may lead to perfectionism or avoidance

ADHD and Anxiety in Adults

Adults with ADHD often describe years of chronic stress before realising ADHD may be part of the picture.

Many have spent years believing they are:

  • lazy

  • disorganised

  • incapable

  • bad at coping

  • “failing” at adulthood

They may experience:

  • constant overwhelm

  • unfinished tasks

  • emotional exhaustion

  • difficulty managing responsibilities

  • chronic guilt and self-criticism

This can create ongoing anxiety about:

  • forgetting things

  • disappointing others

  • missing deadlines

  • underperforming at work

  • appearing incapable

Many adults seek therapy for anxiety before ADHD is ever considered.

At Profound Psychology, this is an extremely common pathway to ADHD diagnosis and/or psychological therapy.

ADHD vs Anxiety: What’s the Difference?

Although ADHD and anxiety overlap, there are important differences.

Anxiety is generally driven by fear, worry, or perceived threat.

ADHD is primarily related to regulation of:

  • attention

  • executive functioning

  • impulses

  • motivation

  • emotions

For example:

A person with anxiety may avoid a task because they are worried about failure.

A person with ADHD may avoid the same task because:

  • they feel mentally paralysed

  • they cannot organise where to begin

  • the task feels overwhelming

  • their brain struggles with initiation

However, the two often interact.

Someone with ADHD may repeatedly struggle with tasks, which then creates anxiety about future performance.

Emotional Dysregulation and Rejection Sensitivity

Many individuals with ADHD experience strong emotional responses.

This may include:

  • frustration

  • shame

  • sensitivity to criticism

  • rejection sensitivity

  • emotional overwhelm

Rejection Sensitivity Dysphoria (RSD) is commonly discussed within ADHD communities and refers to intense emotional pain linked to perceived rejection or criticism.

Children and adults with ADHD may become highly anxious about:

  • making mistakes

  • disappointing people

  • social rejection

  • failure

This emotional sensitivity can significantly affect self-esteem and relationships.

ADHD, Anxiety, and Burnout

Living with unsupported ADHD can become exhausting.

Many individuals spend years:

  • overcompensating

  • masking difficulties

  • trying to stay organised

  • pushing themselves beyond capacity

Eventually, this can contribute to:

  • burnout

  • emotional exhaustion

  • shutdown

  • worsening anxiety symptoms

Some adults reach a point where their coping strategies stop working entirely, this is often the point where people access talking therapy.

ADHD, Autism, and Anxiety

There is also significant overlap between ADHD, autism, and anxiety.

Some individuals experience:

  • sensory overwhelm

  • social exhaustion

  • executive functioning difficulties

  • emotional dysregulation

  • masking

In these situations, anxiety may develop alongside both ADHD and autism.

How Is ADHD and Anxiety Assessed?

A thorough assessment looks beyond surface symptoms to understand:

  • developmental history

  • attention and executive functioning

  • emotional regulation

  • coping strategies

  • school/work functioning

  • sensory experiences

  • anxiety patterns

At Profound Psychology, we understand how easily ADHD can be overlooked when anxiety appears more visible.

Our ADHD assessments aim to understand the full picture rather than focusing on symptoms in isolation.

Support Strategies for ADHD and Anxiety

Support depends on the individual profile, but may include:

  • psychoeducation

  • emotional regulation strategies

  • executive functioning support

  • sensory regulation

  • Psychological Therapy

  • school or workplace adjustments

  • ADHD medication where appropriate

Importantly, treating anxiety alone may not fully help if underlying ADHD remains unrecognised.
