Hello Callie parasites are always a contributing factor.
I must also add that the Liver Flush did not make you worse, though you might have felt worse.
In (self) healing, there is an ideal sequence of healing events leading to improvement ... and maybe for you, the Liver Flush should have happened later in the sequence, not so soon .. but it conferred benefits, nonetheless, perhaps yet unrealized.
Chronic fatigue, low immunity, Depression etc ... the twin causes are nearly always the same:
1/ a weakened, low-immune & mineral-deficient state
2/ a system beset by opportunistic organisms - parasites (this is the way of life and perfectly natural), as is the case in all ecosystems.
I wish you well.
For me it gets worse before it gets better.
But it does get better, with persistence and a good plan.
