Worried

Doctor called with my antibody test results. My regular doctor is out for awhile, so her associate called.  She was wondering what sort of illness we were looking for.  Had to explain that I have been in remission for 20 years with MG & some symptoms have returned. She said that my antibodies were 40 & they should be under 20. Well it's been a long time so I don't really understand how the count works. She is having me do the test again in a month, if it is higher or the same I will once again be seeing a neuro. So worrying has set in.  For some reason it almost feels more scary this time, I guess knowing what could be ahead of me is worst than when I was young & didn't know. I always knew it was a possibility, but I guess I just didn't think it would.
