They're redoing my blood work to see if they can find anything else out (could have been a false positive on my original blood work), and I'll get those results in three weeks. Then he wants to see me again in another six months.
As to the cause of my symptoms, they said that sometimes it could just be viral, so we're keeping our fingers crossed that that's what it was! (I forgot to tell him about when I played with mercury when I was a kid.)
I am just so relieved that he's not worried about it. I'm almost certain that God was testing me in this season of my life. I think He wanted to see if I'd still love Him and trust Him even if I got the rug pulled out from under me. Did I really believe that He's good ALL the time?
