There is a significant disparity in opinions regarding the causes of borderline personality disorder. Although the exact cause remains unclear, several factors have been identified that could potentially contribute to a diagnosis of BPD.

• trauma suffered as a child
• childhood abuse or neglect
• childhood abandonment
• genetics

It is important to bear in mind that an individual living with BPD should not be held responsible for their diagnosis. The diagnosis of BPD is not a result of their actions or lack thereof. Frequently, individuals who receive a BPD diagnosis tend to blame themselves, searching for ways they could have acted differently. However, it is imperative to acknowledge that this is not their fault and to always remember this.
