I was asked to comment on the psychodynamics of autoimmune disorders.
People sometimes associate physical disorders with psychodynamic patterns. It is sometimes accurate.
Regarding autoimmune disorders, the body is attacking itself. The idea then would be that one is attacking ones self psychodynamically, perhaps some sort of self-loathing or self-judgment on some level. It is generally cloaked with denial. You need to decide for yourself if this applies to you and if so how.
Similarly, allergies to the environment can imply aversion to what is around you. Again, one must decide for ones self if this applies to them or not.
