I think the issue being remarked on is while yes therapy helps one better manage and attempt to do everything within an individual’s power to react to something (include minimizing contact) there are enough stressors beyond people’s individual locus of control that no matter how personally resilient one becomes misery is still a natural outcome. Therapy attempts to address underlying causes… But ultimately it still places the burden of fortitude on the person. If the situation merits more fortitude than person is capable of even at their best then the solution lies beyond that individual’s training to respond to it and must be addressed at the source. Hence the phrase “Treats symptoms, not the cause” is catch-phrasy and not by all means technically correct, but encapsulates this frustration at having to constantly be the one expected to exert constant personal effort to be okay while the source problems, which are often cultural/social in nature, are treated as immovable constants and continue being a source of inhumane conditions.
