DBLC, just as a side note... parasites (and I'm sure many other pathogens) can cause low mood. When I first got sick I was in such a black hole depression. But it was like I could step outside of myself and understand that it wasn't really me that was depressed. It was definitely a feeling that had a medical cause. I felt very much like a moody teenager.
Sorry you are going through all this stress:( Good for you for taking care of yourself physically during all of it.
