Trauma is often associated with extreme experiences such as war, violent crime, or natural disasters. While these events can be deeply traumatic, trauma can also result from experiences that are less visible but equally overwhelming. In fact, most people will experience at least one traumatic event in their lifetime.
Trauma occurs when a situation exceeds a person’s ability to cope, leaving a lasting impact on the nervous system, emotions, and sense of safety. Trauma is commonly grouped into three categories:
Acute Trauma: This type of trauma results from a single, overwhelming event such as a car accident, medical emergency, or natural disaster. Emotional and physical reactions are often immediate and intense. While some individuals recover naturally, others may continue to experience anxiety or mood changes long after the event.
Chronic Trauma: Chronic trauma develops through repeated or prolonged exposure to distressing situations, such as ongoing abuse, neglect, bullying, or living in unsafe environments. Over time, the body may remain in a constant state of stress, increasing the risk of anxiety and depression.
Complex Trauma: Complex trauma typically arises from repeated interpersonal harm, often within close relationships or during childhood. This form of trauma can affect emotional regulation, self-esteem, attachment, and the ability to feel safe with others.
Understanding these different types of trauma is important, as each can affect mental health differently and may require a tailored therapeutic approach.
When trauma is not fully processed, the brain and body may continue to react as though the threat is still present. This ongoing survival response can develop into anxiety, even when there is no immediate danger.
Unresolved trauma can contribute to anxiety in several ways:
These reactions are protective responses that once helped the body cope with danger. With time and support, they can be gently retrained.
Just as unresolved trauma can lead to anxiety, it can also contribute to depression. While anxiety reflects a state of hyper-alertness, depression often develops when the nervous system becomes exhausted after prolonged stress.
Trauma-related depression may be characterized by:
Depression following trauma is not a personal failure. It is often a sign that the body and mind have been overwhelmed for too long without adequate support.
Rather than appearing as isolated conditions, anxiety and depression related to trauma often reflect how the nervous system has adapted to ongoing stress. Symptoms may show up emotionally, physically, or behaviourally, and they can change over time.
Some individuals notice symptoms immediately after a traumatic experience, while others may not feel the effects until months or even years later. Trauma responses are shaped by many factors, including past experiences, available support, and ongoing life stressors.
Recognizing that these symptoms are trauma responses — not personal weaknesses — can reduce self-blame and encourage people to seek appropriate care and support.
Therapy can play a powerful role in healing unresolved trauma and reducing symptoms of anxiety and depression. Two evidence-based approaches commonly used are Cognitive Behavioural Therapy (CBT) and Eye Movement Desensitization and Reprocessing (EMDR).
Cognitive Behavioural Therapy (CBT): CBT helps individuals identify and change unhelpful thought patterns and behaviours that maintain anxiety and depression. It provides practical tools for emotional regulation, stress management, and coping. CBT is structured, goal-focused, and often produces noticeable improvements within a defined number of sessions.
Eye Movement Desensitization and Reprocessing (EMDR): EMDR focuses on how traumatic memories are stored in the brain. Through bilateral stimulation, such as guided eye movements or tapping, EMDR helps the brain reprocess distressing memories so they no longer feel overwhelming. Many clients experience reduced emotional intensity and physical distress after EMDR therapy.
Both therapies are trauma-informed and tailored to meet each individual’s unique needs and goals.
Healing from trauma is not about forgetting the past — it is about learning how to feel safe, grounded, and present again. Seeking professional support can be an important step toward improving mental health and overall well-being.
