In yesterday's Office of Readings, St. John Vianney recommended prayer and love. There is nothing very newsworthy in that: Guess what, a saint recommends prayer! And yet, I think that if more people would follow his recommendation we would not see a news report that 10% of Americans are on antidepressants. That is a lot of people who feel depressed.
Here is my prescription. Pray for at least 10 minutes in the morning. I will amplify that a bit. Pray with your thoughts -- "mental prayer" -- by allowing yourself to be in God's presence and staying there, beginning with 10 minutes a day. A good way to do this is to pray by thinking about a Gospel text, perhaps the Gospel of the day. Allow the time to increase as you get used to it, up to 30 minutes. Most importantly, do it every day! In the morning.
