I was just reading this symptom list for Babesia (i finally started treating it with Mepron 3 months ago)
www.gordonmedical.com/unravelling-complex-chronic-illness/babesia-like-organisms-bablo-consideration-signs-and-symptoms/These two from the list:
-Severe depression (can have suicidal ideation).
-Fear! Fear!, Fear!, OCD, anxiety to panic.
Sounds like the Artemisinin is causing a herx for you.
I am seeing several in that list that I was attributing to lyme or bart..but could be Babesia..
When I took Art - I herxed with shivering and once with anxiety....I'd have to check my notes to see what else.
