I can be man made or can be found naturally. I cannot sit still and I wander the world. If one were to claim me as theres they would not be believed, until seen by a doctor then they may see.

This riddle cleverly points to depression, a complex mental health condition that impacts millions worldwide. The first clue, "I can be man made or can be found naturally," highlights the dual nature of its origins. While some individuals may experience depression due to life circumstances, trauma, or ongoing stress, often referred to as "man-made" factors, others may have a genetic predisposition or biological imbalances that contribute to the condition, suggesting a more "natural" or inherent component. It's often a combination of these elements that leads to its development.

The idea that depression "cannot sit still and wanders the world" speaks to its widespread prevalence. Depression is not confined to one place, culture, or demographic; it affects people from all walks of life across the globe. It is a leading cause of disability worldwide, demonstrating its pervasive nature and how it moves through populations, impacting individuals regardless of their background or location.

Finally, the most poignant clue, "If one were to claim me as theres they would not be believed, until seen by a doctor then they may see," addresses the unfortunate stigma and misunderstanding often associated with mental health. Many people who experience symptoms of depression may struggle to be taken seriously by others, or even by themselves, without professional validation. A diagnosis from a doctor or mental health professional not only legitimizes their experience but also is a crucial step towards understanding, acceptance, and finding effective treatment pathways.
