The psyche, like the life of matter, soul and spirit, is limitless, but the forms through which it appears to us are limited. These limitations are associated with the accessibility and explainability for us of a particular phenomenon, and these accessibility and explainability are associated with language, which develops like a cutting tool that requires sharpening or a special configuration. Emotions and feelings are easily put into form, which are captured by the “inner observing eye”, when these phenomena are bright and clearly “foam” the mental tissue, at the same time there are things that are difficult to articulate and understand. For me, such a phenomenon was resentment that arose in the process of co-creation (while writing an article), and this word was not found immediately. At first there was a feeling of separation from something valuable and important, and in this space of separation I caught the thought that “I am not needed,” “I am not loved.” Following this, a feeling appeared that I was losing power, i.e. control over the situation, further, that inside there was a ban on my need to be with another, and I felt fear that I was beginning to feel a sense of excessive need for a person and dependence on him. Trying to understand my condition, going through possible options that explain what is happening: transferences, countertransferences, confluence, retroflection, proflection and other methods of resistance to contact that could participate in the formation of this phenomenon, I came across the word resentment, which most suited the experience that arose. Due to the length of the therapist’s practice, I thought that I was free from this experience and had long gone through all the necessary stages of working through my traumatic experience, which held archaic relationships with other people. And that I am free from codependency and other “troubles” that “ordinary people” suffer from (this is about my narcissism). It turned out - no, I was hooked, and this launched the process of awareness and attempts to explain to myself what was happening. When a strong feeling arises, everything is clear. It is clear why disgust, anger, a desire for revenge arises in response to rejection, etc. And when it is so minimized, hidden, then, I think, many, not only me, may experience bewilderment and confusion associated with the unexpectedness of the “trick” produced by the psyche (going beyond the “conscious - unconscious” format). Perhaps I am mythologizing and mystifying this “trick”. On the other hand, I realize the importance and universality of resentment as a phenomenon of human interactions. What does resentment signal? The first thoughts that arose during communication: “I am not needed”, “they don’t love me”, are associated with childhood experiences, which explain only part of the phenomenon. “As an adult,” my need to be with a person turns out to be not valuable to him, they seem to reject me without rejecting me. If this is manipulation, then it is too subtle a manipulation to be successful. This is a spontaneous action performed by a communication partner that negates the prospects of our interaction. It was as if my movement towards or deeper into this person was blocked. Later, when discussing what happened between us, he developed a feeling of shame and guilt, as a complimentary response to my offense. The duration of the flashing feeling took much less time than its discussion and description, but this introspection of the phenomenon helped me realize many things that had become blurred in the process of work and were perceived stereotypically. For example, I realized that chronic resentment towards their mothers in girls with eating disorders maintains their interactions in “non-contact”, “unloving”, “uselessness”, these interactions are filled with excessive control on the part of the mother over the needs, desires, actions of the daughter, not enough of this , and processes occurring in the body. To the extent that this form of interaction is difficult for both mother and daughter to comprehend, the daughter physically reacts to the mother’s control and intolerance with disgust and vomiting. Often, resentment and disgust develop into.
