Repenting from Anxiety

A dear friend told me he recently had spent time repenting from anxiety that was filling his heart over some issues.

This thought hit me like a 2x4 to the forehead. I'm not sure I realized I should repent from anxiety; my usual strategy is just work harder to stop being anxious and trust God more. "I mean, really, we should save repentence for more serious stuff, right?"

Repentence is the way, not the sometimes when it's obvious I have no other options way.
