Understanding Anxiety and Depression
Learn what anxiety and depression actually are, how to recognise the signs in yourself and others, and where to find help.
Normal Worry vs Anxiety — What’s the Difference?
Everyone worries sometimes — that’s completely normal. But anxiety is something different. The easiest way to tell them apart is to think about a dial: normal worry turns up for a specific reason, then turns back down. Anxiety is when the worry dial gets stuck on high.
Normal Worry
- ✓A reaction to a specific situation — e.g. feeling nervous before a test
- ✓Goes away when the situation passes
- ✓Doesn’t stop you getting on with your life
- ✓Everyone experiences this — it’s a normal part of life
Anxiety (a mental health condition)
- ●Worry that is persistent — it doesn’t go away on its own
- ●Worry that is disproportionate — the feeling is much bigger than the situation warrants
- ●Interferes with daily life — school, friendships, sleep
- ●Can happen without an obvious trigger
Key message: Everyone worries — anxiety is when the worry dial gets stuck on high. It’s not a character flaw or a sign of weakness. It’s a health condition, just like asthma or diabetes.
What Anxiety Feels Like
Anxiety doesn’t just happen in your mind — your body feels it too. Recognising these signs in yourself is a really useful skill.
In your body
- • Racing or pounding heart
- • Shortness of breath
- • Feeling shaky or tense
- • Stomach aches or nausea
- • Headaches
- • Feeling sweaty or suddenly cold
- • Trouble sleeping
- • Tiredness, even after rest
In your mind
- • “What if” thoughts that won’t stop
- • Expecting the worst to happen
- • Feeling on edge or easily irritated
- • Trouble concentrating
- • Replaying events or conversations over and over
Thought patterns in anxiety
Anxiety often comes with specific thinking styles that make things feel worse than they are:
“This will be a total disaster.” Jumping straight to the worst possible outcome.
“Everyone thinks I’m stupid.” Assuming you know what others are thinking — usually negatively.
“I know I’m going to fail.” Predicting the future as definitely bad.
Important: The physical symptoms of anxiety — the racing heart, the shaky feeling — are your body’s alarm system going off. They feel awful, but they are not dangerous. Your body is trying to protect you. The alarm is just a little over-sensitive.
Normal Sadness vs Depression — What’s the Difference?
Feeling sad is part of being human. But depression is more than sadness — it is a health condition that changes how the brain works, and it needs real support to get better.
Normal Sadness
- ✓A response to something difficult — a loss, a disappointment, a hard day
- ✓Comes and goes — you still have good moments
- ✓Painful, but bearable — you can still function
- ✓Doesn’t take away all positive feelings
Depression (a mental health condition)
- ●Persistent low mood most of the day, nearly every day, for 2+ weeks
- ●Loss of interest in things you used to enjoy
- ●Feeling empty rather than just sad
- ●Affects eating, sleeping, concentration, and motivation
- ●Can happen without an obvious cause
Key message: Depression is not just “feeling sad” or “having a bad week.” It is a health condition that affects how the brain works — specifically the chemicals and pathways involved in mood and motivation. Like any health condition, it responds to the right support and treatment.
Myths and Facts About Mental Health
There is a lot of misinformation about mental health. Getting the facts straight makes it easier to support yourself and others.
Myth
Mental health problems are rare
Fact
1 in 4 people will experience a mental health condition in their lifetime. It is one of the most common health issues there is.
Myth
You can just “snap out of it”
Fact
Mental health conditions involve brain chemistry. Telling someone to snap out of depression is like telling someone to snap out of a broken leg — it doesn’t work that way.
Myth
Seeking help is weak
Fact
Recognising you need support and actually reaching out takes real courage and self-awareness. It is one of the strongest things a person can do.
Myth
Only certain kinds of people get anxiety or depression
Fact
These conditions affect people of every background, intelligence level, and personality type. High achievers, confident people, and popular students all experience mental health challenges.
When to Get Help
Consider speaking to someone you trust if you or a friend has been experiencing any of the following for more than two weeks:
- ● Feeling very low, empty, or hopeless most of the time
- ● Losing interest in things you used to enjoy
- ● Worrying so much it is getting in the way of school, friendships, or sleep
- ! Having thoughts of hurting yourself — please tell a trusted adult right away
- ● Struggling to leave the house or attend school because of fear or dread
Key message: Getting help early makes a huge difference. Anxiety and depression are very treatable — most people who get the right support feel significantly better. You do not have to wait until things get really bad.
How to Support a Friend
If someone you care about is struggling, knowing what to say — and what not to say — can make a real difference.
What TO do
- ✓Listen without judging
- ✓Ask “Are you okay?” and genuinely wait for the answer
- ✓Say “I’m here for you”
- ✓Let them talk without trying to fix everything
- ✓Encourage them to speak to a trusted adult
What NOT to do
- ✗Don’t say “you have nothing to be upset about”
- ✗Don’t compare their situation to others
- ✗Don’t promise to keep serious concerns a secret
- ✗Don’t try to diagnose them
If you are worried a friend is in danger: Tell a trusted adult immediately. This is not betraying them — it is protecting them. A real friend gets help when it matters most.
