I've given it some thought, and my One Word is the same as it was for 2013: PEACE. Not as much because of panic attacks, but because of daily challenges.
I still experience anxiety, but the panic attacks have lessened, thank the Lord. I think that, because I'm often in "survival mode," I have a hard time dealing with normal stress: disharmony, pressure, changing plans. At those times I start praying, but the emotions have already hit: I'm already bordering on frantic.
I'm still working with the excellent doctor I found last summer, and I'm still working with my (also excellent) counselor. I continue to give myself permission to take care of myself. My devotional book for this year is subtitled "Becoming a Woman at Peace."
So I'm working diligently on this and trying to attack it from all angles. Maybe for 2015 I can choose a different word! :)
