That roller coaster sounds pretty typical. I'm having good weeks at a time, then crash.
My chest pains also came back - it's unresolved Babesia, and just found out I'm positive for Bartonella too.
The good news about
them coming back is that they ever went away in the first place
Keep remembering those good days. Knowing that there IS progress really helps me through. When I'm having a bad day, I feel like its never going to end and get depressed. So I write all the time about
my good days so I'm sure to remember it will get better.
