I learned that the only way to overcome anxiety, the only way to get better is to be willing to not get better. I know that sounds like it doesn't make any sense. In other words, you must accept that the feelings (which are both emotional AND physical) might never leave and choose to live to the fullest anyway. It is the lack of acceptance, the desire to escape the sensation, that fuels its continuation.
When I consciously, and as an act of will, chose to embrace the anxiety as a sacrificial offering to my God I started to get better. It still took some time. I had to consciously accept repeatedly. But there was an immediate lessening of symptoms that continued until I felt completely normal again.
I am still amazed by this. It is in being willing to have things never change that they will change. It is in losing our life that we gain it. Blessed be God.
