I need to find out if my health insurance plans cover psychologist visits and mental illnesses. Thanks!

I need 2 professional articles (Like from Social workers or PHDs) and 3 popular media articles about mental health for a project. I was wondering if someone would like to show me some, or lead me to a site that had some decent professional articles, since those are the hardest to find.
