Final answer:
Individuals not sufficiently individuated from their family tend to be overwhelmed in stressful family situations, due to a lack of resilience and personal coping mechanisms.
Step-by-step explanation:
Individuals who are not sufficiently individuated from the family of origin are likely to be overwhelmed when stressful situations arise involving family members. The process of individuation involves developing a sense of identity that is distinct and separate from family members. It leads to increased feelings of independence and individuality. A lack of individuation may mean that an individual hasn't developed the resilience and coping mechanisms necessary to handle stress independently from their family system.
Those who have achieved a strong sense of self are better equipped to maintain healthy boundaries and respond to stress effectively. Conversely, when an individual relies heavily on the family unit to define their sense of self, stressful situations involving the family may lead to feelings of being overwhelmed due to the lack of strong personal boundaries and individual coping strategies.
