Finding the right article starts with using the right database. There are quite a few databases that can help you, but in order to choose the right one, you have to narrow down your topic/focus. Since databases are divided in broad areas, think about one or two that best fits your topic.
See the examples below:
Mental illness: depression, substance abuse, suicide, anxiety
Self-help and resilience: self-care, counseling, counseling efforts, support systems
Addiction: drug addiction, alcohol addiction, substance addiction and abuse
