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.

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.

Support Strategies for ADHD and Anxiety
Support depends on the individual profile, but may include:

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