Two helps with anxiety. (1) Think about the right thing. Problems require some thought, some attention, but fixation? Probably not. Obsessing? Nope. Scripture tells us to be careful what we ponder. Not talking here about positive thinking, but Godward thinking. Intentionally direct your mind to God. Meditate on His Word. So, think right and, (2) do the right thing: obey. Practice the things Jesus taught us, and we'll have less time to worry about us. Focus shifting from us to God and others causes anxiety to lose its grip.
