That point about Tefillah and depression is right on. But Tefilla and Emunah are intertwined. The more Emuna you have the more Kavana you daven with and the more Kavana you Daven with the more Emunah you will have.
People don’t appreciate that they can talk to Hashem whenever wherever (as long as its not a bathroom..)
Hashem listens to all of our prayers in any language. If you are at work and you feel like you need help take 15 seconds to say Hashem, I know you run the world and control everything and man is powerless without You please help me, please give me Hatzlacha in this….
