Is depression generally more revolved around discontent with your past, or your genetic attributes?

Depression can be a mixture of both. Sometimes you are genetically predisposed to develop depression and sometimes your environment influences how we interact with the world and experience depression. From early childhood into adulthood, everything from Adverse Childhood Experiences (ACEs) to experiences as adults can influence our emotional state. Things like poverty, workplace and homelife stress, abuse, and other adverse experiences can contribute to how we experience depression, and even if we experience depression. Other things that influence depression could be drug and alcohol use. So ultimately, the question above is limited. it can be both, or neither. Depression is a complicated thing influenced by many different factors.
