Changes to Plans and Routine Make Me Extremely Anxious or Overwhelmed
A cancelled train, somebody arriving early, a meeting moving rooms or a plan changing at the last minute can seem minor to other people and feel enormous to you.
A cancelled train, somebody arriving early, a meeting moving rooms or a plan changing at the last minute can seem minor to other people and feel enormous to you.
For some autistic people, predictability and routine reduce the amount of uncertainty that has to be processed. NHS guidance recognises distress around changes to routine, and NHS England notes that change and uncertainty can be highly distressing for some autistic adults.
That does not mean everybody who dislikes change is autistic. The useful question is what the change actually does to you.
The problem may be losing the map, not losing your preference
A plan gives the day a shape.
You know when to leave, what will happen, who will be there, what you need and what comes afterwards. When the plan changes, several decisions may suddenly need to be remade at once.
That can create a genuine processing load. “We’ll just work it out when we get there” may sound reassuring to somebody else and make the situation less manageable for you.
Notice which kinds of uncertainty are hardest
Is it sudden timing changes? Not knowing where you will sit? A different person attending? Being unable to predict when something will finish? Having several possible outcomes?
The more precisely you understand the uncertainty, the easier it is to ask for useful information.
You may not need every detail. You may need the particular details that allow you to build a workable mental picture.
Create a Plan B before you need it
For predictable sources of disruption, decide in advance what the alternative will be.
If public transport fails, what is the next route? If an appointment is delayed, where could you wait? If plans with friends change, what information do you need before deciding whether you can still go?
A backup plan does not remove uncertainty, but it reduces the number of decisions arriving at the most stressful moment.
Ask people to communicate changes clearly
Where possible, ask for changes to be explained directly rather than hinted at.
At work or in healthcare, clear information about altered times, locations, people or expectations may make a significant difference. NICE recommends adapting communication and environments to individual autistic needs.
You do not need to apologise for finding clear information useful.
When anxiety about change is taking over
If your need for predictability is part of a broader lifelong pattern involving social communication, sensory differences or other autistic features, you may want to discuss autism assessment with your GP.
If anxiety itself is becoming severe or restricting your life, ask for mental-health support too. Autism and anxiety can coexist; support for one should not depend on ignoring the other.

Important autism, ADHD and mental health information
This guide provides general information only and is not a diagnosis or a substitute for professional medical or mental-health advice. Autistic people and people with ADHD are individuals, and experiences of communication, routine, sensory processing, attention, organisation, relationships and mental wellbeing can vary greatly.
Recognising autistic or ADHD traits does not by itself establish a diagnosis. Autism and ADHD assessments should be undertaken by appropriately trained and competent healthcare professionals and should consider developmental history, current life and functioning, other health or neurodevelopmental conditions, and the person’s individual experiences.
If difficulties are persistent or significantly affecting everyday life or mental wellbeing, speak to your GP, assessment service or another appropriately qualified healthcare professional about what support may be appropriate.
Do not start, stop or change prescribed medication based on information in this guide. Medication decisions should be discussed with the clinician responsible for your care.
