A client is admitted to the psychiatric inpatient unit with a bandaged flesh wound after attempting self injury by shooting. The client reports going through a divorce one year ago, job loss four months ago, and suffering from a breakup of a current relationship last week. Which is the most likely source of this client's current feelings of depression?

A) While frustration may contribute to the client's distress, it's not the primary source described in the scenario. B) The client has experienced multiple losses, including divorce, job loss, and breakup, which are significant sources of grief and depression. C) Poor self-esteem could be a contributing factor, but it's not directly mentioned as the primary source of depression in the scenario. D) Lack of intimate relationships may exacerbate feelings of loneliness but may not be the primary source of depression compared to the losses experienced.
