I've read in other forums where you've posted that you'd experienced great pain with your 1st marriage and are currently in the most ideal marriage for you at this time.
Could your chostrochondritis be resultant of that experience and the emotions that the marriage generated? Is there anything currently occurring in your life or psyche that is generating these same feelings?
Admittedly I don't know the details of when you contracted and maintained the chostro, but could the two be linked somehow?
