1. What Is Autism?
Autism is a lifelong neurodevelopmental condition that affects how a person communicates, interacts, and experiences the world. It is described as a spectrum because each autistic person has their own unique strengths and challenges.
Recent research from Newcastle University and the University of Cambridge estimates that 1 in 57 children in the UK are on the autism spectrum, higher than the often-cited 1 in 100 figure. Many adults remain undiagnosed, especially women and people assigned female at birth, who often mask their traits.
2. Recognising Signs of Autism
Common traits in autistic people
- Feeling overwhelmed in busy or unfamiliar settings
- Needing clear routine and structure to feel safe
- Struggling with eye contact or small talk
- Deep focus on specific interests
- Sensory differences (sensitive to noise, light, or texture)
- Repetitive behaviours (like rocking or stimming)
- Finding social rules confusing or draining
People often discover they are autistic after years of anxiety, burnout, or feeling “out of step” with others.
3. Coping with Anxiety and Building Routine
Why anxiety is common in autistic people
Studies show that around 40% of autistic people also experience clinical anxiety (van Steensel et al., 2011). Anxiety in autism may show up as:
- Avoidance (e.g. refusing school or work)
- Repetitive movements or routines to regain control
- Overthinking and fear of change
- Meltdowns or shutdowns when overwhelmed
Autistic people often experience anxiety differently to neurotypical people. The root causes may include sensory overload, difficulty identifying emotions (alexithymia), or a strong need for predictability in a world that feels uncertain.
Ways to manage anxiety:
- Self-soothing through routines, calming activities, or special interests
- Problem-solving skills to build confidence
- Environmental adaptations like noise-cancelling headphones or clear schedules
- Reasonable adjustments at work or school
- Professional support, such as modified CBT with an autism-aware therapist
- Speaking to a GP about therapy or medication if appropriate
Building routine is also key. Structure helps reduce anxiety and builds confidence in day-to-day life.
4. Why Getting an Autism Diagnosis Can Be Life-Changing
A formal diagnosis helps explain lifelong patterns and opens up support.
Diagnosis can:
- Help you understand your identity
- Provide access to workplace or school adjustments
- Reduce anxiety by validating your experiences
- Support referrals to therapy, coaching, or autism-informed services
NHS waiting times
Although NHS assessments are free, waiting lists are long. As of late 2024:
- 204,876 people were waiting for an autism assessment in England
- 89% had waited longer than the recommended 13 weeks
(Source: National Autistic Society)
Many people face a wait of 12 months or more, with no clear timeline or support in the meantime.

7. FAQ: Anxiety as an Autistic Person
What causes anxiety in autistic people?
Anxiety can come from sensory overload, difficulty recognising emotions, or fear of unexpected change. Autistic people often rely on routine to reduce stress, so disruptions can feel overwhelming.
How does anxiety look in an autistic person?
You might notice:
- Increased repetition or insistence on routine
- Avoiding social situations or school
- Asking for lots of reassurance
- Meltdowns or running away from distress
- Hyperfocus or overthinking
These behaviours are ways of coping with uncertainty or sensory distress.
What helps?
- Regular rest and downtime
- Calming environments (low light, quiet spaces)
- Clear expectations and visual schedules
- Autistic-led therapy (like adapted CBT)
- Permission to stim or follow routines
- Supportive workplaces and schools
