Instead of focusing solely on the feelings your child expresses, look at what their worries are preventing them from doing. This is the single most important indicator. Pay close attention to these areas:
School: Are they frequently complaining of physical symptoms like headaches or stomach-aches on school days, but not on weekends? Do they refuse to get on the school bus or have a history of frequent calls for early pick-up? This can manifest as a middle-schooler who, before every science class, gets a stomach-ache that's so severe it sends them to the nurse's office. The anxiety isn't about the class itself, but the fear of having to do a presentation or a group project in front of peers, and the physical symptoms are a real manifestation of that stress.
Daily Tasks and Routines: Do small tasks take an excessive amount of time? Do they get "stuck" in a cycle of needing to do things a certain way? For instance, they might spend 20 minutes arranging their school supplies exactly right before they can start their homework, or they might repeatedly check the stove to make sure it's off, even though they know it is. These behaviours, known as compulsions, are often performed to reduce anxiety, but they end up consuming a significant portion of their time and energy, interfering with their ability to complete everyday tasks.
Sometimes, what appears to be anxiety is a symptom of something else. It's important to be a detective and look for other clues.
ADHD: A child with Attention-Deficit/Hyperactivity Disorder might seem anxious or restless, but their underlying challenge is with focus and impulse control. They might blurt out an answer in class and then worry about what their friends think, but the initial behaviour was not driven by anxiety. An anxious child, in contrast, might be too worried to even raise their hand. The core difference is the driver of the behaviour. Is it a difficulty with self-regulation, or is it a fear of negative outcomes?
OCD: Obsessive-Compulsive Disorder is a related condition — classified separately from anxiety disorders since DSM-5 — characterized by persistent, unwanted thoughts (obsessions) and the need to perform specific behaviours (compulsions) to get rid of them. While an anxious child might worry about germs, a child with OCD feels a compulsion to engage in a specific, repetitive action to neutralize that worry, like washing their hands for a precise amount of time. They may be tormented by intrusive thoughts that lead to these ritualistic behaviours. The key differentiator is the presence of these repetitive rituals that are done to reduce distress.
There are certain situations where you shouldn't hesitate. Contact a healthcare professional or a mental health specialist immediately if you notice:
Self-harm: Any talk about hurting themselves or evidence of self-injurious behaviours, such as cutting or burning. This is an immediate sign that your child is in severe distress and needs professional intervention to learn healthier coping mechanisms.
Suicidal Thoughts: Any statements about wanting to die or feeling like life is not worth living. Take every statement seriously, even if it seems like a passing comment. These thoughts are a clear indication of a mental health crisis. If your child talks about wanting to die, has harmed themselves, or you believe they are in immediate danger, do not wait for an appointment — take them to the nearest emergency department.
Panic Attacks: Episodes of intense fear accompanied by physical symptoms like a racing heart, chest pain, dizziness, or a feeling of losing control. These attacks can be terrifying for a child and are a sign that their anxiety has become so severe it is manifesting physically.
