Borderline personality disorder
Sense of self and self-concept

Individuals diagnosed with BPD frequently experience significant difficulties in maintaining a stable self-concept. This instability manifests as uncertainty in personal values, beliefs, preferences, and interests. They may also express confusion regarding their aspirations and objectives in terms of relationships and career paths. Such indeterminacy leads to feelings of emptiness and a profound sense of disorientation regarding their own identity. Moreover, their self-perception can fluctuate dramatically over short periods, oscillating between positive and negative evaluations. Consequently, individuals with BPD might adopt their sense of self based on their surroundings or the people they interact with, resulting in a chameleon-like adaptation of identity.
