I go through periods where just thinking about my breath flow can be the catalyst for hours of anxiety.
I'll be feeling OK, energetic, and unanxious, then I'll think about my breathing for a moment, and within minutes I'll be feeling increasingly anxious, with weakness & acheyness all through my body.
Sometimes I've noticed that, upon thinking about my breath, I might halt it for a second, or become so conscious of it that I automatically change its flow - a few longer or shorter inhales/exhales - and I originally thought that's what was causing the cascade of symptoms. But lately, it seems even if I don't make any changes to my breathing, just notice it, the symptoms come on anyway. Once they appear, I often feel seriously anxious, weak and sore for hours before it finally subsides and I feel normal again. Weird. Anyone experience this too, or have a reliable countermeasure for reversing it or snapping out if it?
