We are located in Mississippi, USA - out of country orders can take a while to arrive due to customs.
The toxins put off by parasites cross the myelin sheath that covers the brain - this causes the Central Nervous System to be irritated - when the CNS gets irritated, all sorts of mental disturbances can occur including depression, mood swings, anxiety, panic attacks, brain fog, etc.
Hopefully - when the parasites are gone, the toxin levels will come down and your mood will stabilize.
