My doctor's office called, and my test was negative, so I don't need a gastro workup at the moment. I'm not good at feeling relief. I have 35 years of practice at immediately beginning to worry about something else. But I am making progress--I did recognize that I was glad not to have an invasive procedure. My doctor prescribed an iron supplement for the next 6 weeks or so, and then I get another blood test to see if my hemoglobin goes up, and then we go from there. My OCD doesn't like this, but there's no way to definitively capture what is happening in my body for all time. This kind of diagnostic omniscience is not available, as much as my desire for absolute certainty keeps knocking at the door. I was proud of myself for only spending a few minutes reading about iron supplements, before buying a bottle and taking a dose. In the past I'd still be in research mode, planning the perfect method for ingesting the perfect iron product at exactly the right time, and driving myself crazy.
