How to distinguish herx and flare?

I started taking Artemisia for Babesia one month ago (500mg pill/day). I took it for 10 days then I felt bad,
air hunger, chills, fatigue, headache. Problem is that, for those few days, I had more stress because of my work
(I work from home) and then I stopped taking Artemisia for next 10 days, only took antioxidans and epstom salt.
And in few days I felt better.

10 days ago I started Artemisia again and it happened again that I had more stress with work and last few days I feel bad again.

Now I can't say what causes that?
Is it flare happens because of stress? Or is it herx?

Thanks Rikky1, I'm taking whole plant Artemisia annua (Nutricology). I read about it that it is safer then Artemisinin.

Actually I'm self treating with herbs, because I don't think here where I live (Europe/Serbia) is much doctors who know about herbs, or I didn't find one, they usually go with antibiotics. I was taking antibiotics for two months but develop some kind of alergic reaction so I won't take it anymore.

I was first diagnosed with Coxsackie b virus, had problem with my heart (pericarditis), but latter found Borelia and Chlamidia pneumonia positive blood test as well. Got some herbal pills from one doctor but I'm not sure what is name of those in English but he said it is for all bacteria and viruses. Something like general natural antibiotic. I think it helps me but still I have bad days.

Since my main problem is air hunger which happens again when I develop fatigue and chill I read here that it may be Babesia so I took Artemisia to try that for at least month or two...

Still I don't distinguish herx and flare. Is it important to stay away from mental stress and physical activity during treatment?

Thanks Pirouette, do you think I need to add one more herb for Babesia? Honestly I'm scared to take lot of herbs at the same time.

In addition to the cryptolepis and sida acuta rikky suggested - a good support herb to take is Hawthorn. It good for the cardiovascular system.
Babesia can cause issues with heart/blood vessels.

Also CoQ10 supplement is good for the heart.

Over the next week I would lower the Artemesia dose a bit and increase detoxing. More importantly, I would do whatever humanly possible to decrease stress.

Once you get yourself stable again, try increasing the artemesia along with increasing detoxing and rest. This could take a couple weeks - don't rush it. Once you get up to the optimal Artemesia dose, try incorporating suggestions other posters have made - always one thing at a time, always start with low doses and titrate up slowly, always drink enough water, get enough rest and keep the stress down.

I can't tell you how many people I've come across since being on this forum the past almost 4 years who try to continue and maintain "life" while dealing with these illnesses AND treatment. In many ways, it is life's stressors that got people to a state of disease in the first place. We don't see it because we've been doing it for so long. But stress will absolutely interfere with successful treatment. Your body is not a machine.

So, in addition to decreasing stress you also need to slow down. Allow your body to rest as much as possible and when you have things you need to get done, just do them more slowly, reduce all anxiety and urgency out of your day.

All this helps support the parasympathetic nervous system, which can help keep your immune levels supported.

Diet is also critical in keeping immune health optimal since 70% of the immune system is the mucosal lining of our GI.
