Anxiety, Worry & Big Feelings

A gentle, child-friendly guide to understanding worry, anxious feelings, and what helps — at home, at school, and in the moment.

Important

If anything on this page feels too heavy, it’s okay to pause, take a break, and come back later. If a child/young person feels unsafe right now, go to the Get Help section.

“Big feelings are not ‘bad’ — they’re messages. We can learn to listen safely.”

What is anxiety?

Anxiety is what happens when our brain thinks something might be unsafe — even if the danger isn’t actually happening right now. It can feel like worry, fear, “what if” thoughts, or a tight feeling in the body.

Worry is a normal feeling. Anxiety becomes a problem when it feels too big, lasts a long time, or stops someone from doing normal life (like learning, sleeping, eating, or playing).

Helpful way to explain it

“Your brain has an alarm system. Sometimes it goes off too easily — like a smoke alarm that beeps even when toast burns.”

Common triggers
  • Changes and transitions
  • School pressure or tests
  • Friendship worries
  • Separation from caregivers
  • Big events (moves, family stress)

Signs to notice (kids & youth)

Anxiety can show up in thoughts, feelings, body sensations, and behaviour.

In the body
  • Stomach aches, nausea
  • Headaches or feeling dizzy
  • Fast heartbeat or shaky hands
  • Muscle tension, jaw clenching
  • Trouble sleeping
In behaviour
  • Avoiding school, events, or new things
  • Clinginess, tears, “I can’t”
  • Anger, meltdowns, shutdowns
  • Perfectionism or reassurance-seeking
  • Needing lots of control/routines

When to pay extra attention

  • Worry is happening most days for weeks
  • It’s affecting school, friendships, sleep, or eating
  • There are panic-like symptoms (breathing feels hard, chest tightness)
  • The child/young person is talking about hopelessness or feeling unsafe

What helps (in real life)

Different kids need different tools. Try a few and keep what works.

In-the-moment tools
  • Slow breathing: breathe in 4, out 6 (x5)
  • Grounding: 5 things you see, 4 you feel, 3 you hear…
  • Cold water: sip water or wash hands in cool water
  • Safe sensory: weighted lap pad, hoodie, fidget
Daily supports
  • Predictable routines + gentle warnings for changes
  • Movement (walk, trampoline, stretching)
  • “Worry time” (10 minutes then close the worry box)
  • Sleep routine (same time, calm wind-down)

A simple “Worry Plan” script

  • Name it: “This feels like worry/anxiety.”
  • Notice body: “My tummy feels tight.”
  • Do one tool: breathing, grounding, or sensory support.
  • Next tiny step: “What’s one small thing I can do next?”

School support ideas

School can be a huge anxiety trigger — and support at school can make a big difference.

Helpful accommodations
  • Quiet space or calm corner pass
  • Extra time for tests / reduced load
  • Check-in person (teacher aide, counsellor)
  • Visual schedule + warnings for changes
  • Breaks for movement/sensory regulation
What caregivers can say to school

“When anxiety spikes, my child may freeze or melt down. A calm voice + a short break helps them return to learning.”

Calm Corner

Try this quick reset together (1–2 minutes).

1) Breathe

Hand on chest, hand on belly. In for 4… out for 6… repeat 5 times.

2) Ground

Look around: name 5 things you can see. Then 4 things you can feel.

3) Reassure (short + real)

“You’re safe right now. I’m here. We’ll take this one step at a time.”

4) Next step

Choose one tiny action: drink water, sit quietly, or return for 5 minutes of learning/play.

Language matters

The words we use can either calm the nervous system or accidentally make anxiety feel bigger.

Try this instead

  • Instead of: “You’re fine, stop worrying.” Try: “I can see this feels scary. Let’s breathe together.”
  • Instead of: “There’s nothing wrong.” Try: “Your body is having a big alarm moment.”
  • Instead of: “Just be brave.” Try: “We can do one tiny step, then rest.”

When to reach out for extra help

It’s okay to ask for help even if it’s “not that bad.” Support is allowed.

  • Anxiety is frequent and lasting (weeks/months)
  • School refusal, panic symptoms, or constant reassurance seeking
  • Sleep is very disrupted
  • They feel unsafe, hopeless, or talk about not wanting to be here

FAQs

Is anxiety “bad behaviour”?

No. Anxiety is a nervous-system response. Some kids act clingy, avoid things, or melt down because their body feels unsafe.

Can kids have panic attacks?

Yes — panic can happen at any age. If breathing feels hard, chest feels tight, or fear feels sudden and intense, extra support may help.

Should I reassure them every time?

Short reassurance is helpful, but repeated reassurance can feed anxiety. Try: “I’m here. Let’s do a tool.” then guide one small step.

What if anxiety shows up as anger?

That’s common. The body can go into fight mode. Calm voice + space + grounding often works better than lectures in the moment.
