It doesn't make sense to me why people take medication for a mental psychological stress related problem. Medications are meant to be for people to manage symtpoms of physical health issues.
People may think that depression is just related to chemical imbalance or genetic but that is just a belief not a fact,

Some of your statements seem to say you believe all depression is stress related. Stress can be a major factor for many people but not all. The causes of depression are very complex and there are many. Studies on stress find that some people can handle stress very well and others cannot and it can lead to depression. This may be a natural pre disposition or that they did not learn good coping skills or because of previous trauma. In my case when I am not depressed I can handle stress very well, in fact I thrive on it. I often get depressed in times of 0 stress. Depression itself causes stress because of how it affects my life but stress does not cause it in my case.
There is lots of evidence that genetics play a role for many people. It is not just belief. There is also lots of evidence that CBT, new ways of thinking and meditation and the like can change brain chemistry. For many of us through our own experience these methods are not powerful enough to overcome or eliminate depression. They are usually meant to help someone out of a depression when they are already in it but often it does not work. They may have prevented me from going in to them sometimes I can't say for sure. I know I still have them.
Overview of the Genetics of Major Depressive Disorder

Twin and Family Studies
Evidence for a genetic component to mood disorders has been documented consistently using family, twin, and adoption studies. The first genetic studies of mood disorders were conducted more than 70 years ago and included assessment of concordance rates for monozygotic and dizygotic twins with mood disorders [3]. These early studies did not distinguish between bipolar depression and MDD-recurrent unipolar (MDD-RU). A recent review of twin studies in MDD-RU estimated heritability at 37%, with a substantial component of unique individual environmental risk but little shared environmental risk [4].
Family studies of MDD-RU have shown that first-degree relatives of MDD-RU probands are at increased risk of MDD-RU disorders compared with first-degree relatives of control probands [5]. There was a twofold to fourfold increased risk of MDD-RU among the first-degree relatives of MDD-RU probands. Characteristics of MDD-RU disorders that yield a more heritable phenotype include early onset (ie, before age 30 years) and a high degree of recurrence. A third characteristic that may identify a separate group of disorders is the presence of psychosis. Additional genetic subtypes of MDD-RU may be identified through examination of comorbidities with panic disorder, other anxiety disorders, and alcoholism.
