Depression is one of the most common and misunderstood mental health conditions worldwide. Although it can feel isolating, depression is neither rare nor a personal failure. Updated for 2026, this guide is designed to help you understand what depression is, how it can present across different life stages, and when professional support may be helpful.
If you’re looking for clinical support, our team offers professional depression therapy in Calgary and online counselling across Alberta.

What Depression Can Look Like
Depression does not look the same for everyone. Some people experience persistent sadness or emptiness, while others notice irritability, fatigue, or a loss of interest in activities they once enjoyed. For some, symptoms come and go. For others, they persist without support.
Depression Across Life Stages
Children
Depression can occur in childhood and may appear as withdrawal, irritability, or behavioural changes rather than sadness alone. Early awareness and professional guidance can make a significant difference.

Teenagers
Adolescence involves emotional, social, and neurological changes that can increase vulnerability to depression. Symptoms may be mistaken for “typical teenage behaviour,” delaying support.

Adults and Seniors
Depression in older adults is often overlooked or misattributed to aging or physical illness. Recognizing symptoms and seeking appropriate care can improve quality of life at any age.
