Anxiety is a feeling of worry, fear or nervousness. Everyone feels anxious sometimes — it can be helpful when it warns us about danger or helps us prepare.
But anxiety becomes a problem when it is too strong, happens too often, lasts too long, or stops someone from doing everyday things. It can affect school, work, sleep, eating, friendships, family life and physical health.
Anxiety is not weakness. It is not attention-seeking. It is not being dramatic. It is a real mind and body response.
Anxiety is more than "just worrying"
Anxiety can feel like:
- A racing heart, tight chest, butterflies, feeling sick
- Shaking, sweating, headaches, tummy aches, dizziness
- Needing the toilet, feeling hot or cold
- Racing thoughts, panic, a need to escape
- Fear something bad will happen
- Feeling unable to cope
For children, anxiety may not come out as "I feel anxious." It often shows as anger, tears, refusal, clinginess, avoidance, silence, meltdowns, shutdowns or physical complaints.
Anxiety and the brain
Anxiety is linked to the body's survival system. When the brain senses danger, it triggers a fight, flight, freeze or fawn response:
- Fight — shout, argue, lash out, become defensive
- Flight — run away, avoid, leave, hide
- Freeze — shut down, go quiet, feel stuck
- Fawn — people-please, agree, mask, try to keep others happy
These responses are usually not a choice. A child refusing school, hiding under a table or crying before a party may not be "being difficult" — their body may be reacting as if the situation is unsafe.
Common types of anxiety
- Generalised anxiety — worrying about many different things, much of the time
- Separation anxiety — intense distress when away from a parent or trusted person
- Social anxiety — fear of being judged, embarrassed or watched
- Panic attacks — sudden waves of intense fear with strong physical symptoms
- Phobias — intense fear of specific things (dogs, needles, vomit, heights, lifts)
- Health anxiety — repeated worry about illness or body sensations
Anxiety and SEND
Anxiety is very common alongside autism, ADHD, PDA, dyslexia and dyspraxia. It can come from sensory overload, masking, unpredictability, social confusion, repeated school struggles or rejection sensitivity. Support has to address the underlying need, not just the anxious behaviour.
Key message
A child or adult with anxiety is not weak, naughty or dramatic. Their nervous system may be working hard to protect them.
Support begins with understanding. When we reduce shame, notice triggers, offer calm support and build small brave steps, anxiety becomes more manageable.
Small steps matter. Understanding changes everything.
