100%. There is no such thing as a "pathogen", nor an "immune system", nor an "antigen" (nor an "antibody"). Antibodies/Antigens are akin to a temporary super glue that works to hold decaying cells together for a little longer. It is a protein "globulin" that is activated during a dis-ease process.

Bacteria primarily work to break down temporary excess tissue that your body deliberately created to assist you with resolving a psychological conflict. When you resolve the conflict, bacteria arrive at the scene of excess tissue creation and decompose it. The "waste product" of the bacteria creates a putrefaction in your bloodstream which makes you feel sick for a few days while the decomposed waste product is flushed out of your system.

As such, the story of the bacteria qualifies as a "half truth". While it's true, the overactivity of bacteria during the decomposition "make you sick", it is not true that the bacteria "cause sickness" because they "attacked you" and that you "caught them" from "out there". Your body produces bacteria as needed to return you to a state of homeostasis, as you were prior to your psychological conflict.

Net-Net - If you leave your body alone, pay attention to symptoms instead of trying to suppress them, take notice of any pains you feel and avoid exacerbating them, rest as you feel you should, drink fluids as you feel you should (if you feel sick), and ensure you're getting enough protein in your diet when you feel sick (which can be hard to do if you have a low appetite - "bone broth" is the answer if this is the case), then your body will naturally and perfectly heal itself without any outside intervention or "medicines".

In a nutshell, your body knows exactly what it's doing at all times. It never "gets attacked", it never "Mutates out of control", it never "attacks itself" and it never "degenerates" before the age of 125. It will always restore you to perfect health if you are able to Accept/Allow/Forgive/Come-to-Terms-With/Be-At-Peace-With the life events that catch you off guard and cause you worry, upset, grief, fear, anger, etc. etc. The quicker you can resolve these psychological conflicts, which are unavoidable, the less "disease" or complete cessation of them in all categories (germs, toxins, cancers, heart disease, muscle/bone disease, skin, organs, etc.) you will experience in life as they all arise when the psyche works to protect us from our perceived threats.
