In my journey to Christianity I have found that as my faith grew my anxiety and depression became much more manageable. This really wasn't intentional on my part but Ive transitioned from a decade+ of actively managing with medication and weekly therapy to no meds and monthly psychotherapy over a few years. Looking back I do credit that to my faith giving me a framework to manage my long list of worries, concerns and fears. The people in my Church community generally are happy even despite dealing with many difficulties. I can't say the same for all the people I know through work or other venues.
