Suicidal Ideation (thoughts of wanting to kill oneself) are common in those suffering from Borderline Personality Disorder but not a requirement to warrant the diagnosis. Research has shown that up to 80 percent of people with BPD will make at least one suicide attempt in their lifetime, and many will make multiple suicide attempts. People with BPD are also more likely to complete suicide than individuals with any other psychiatric diagnosis. Around 9 percent of people with BPD complete suicide, which is more than 50 times the rate of suicide in the general population.
Due to the very nature of those with BPD (impulsivity, severe emotional pain and the chronicity-lasting for years), those effected are more likely to have chronic suicidal thoughts and at some point act on those thoughts.
It has become common for society to associate suicidal ideation/suicidal gestures with borderline personality disorder. However, one does not have to have chronic suicidal ideation/ history of attempts to have symptoms/a diagnosis of BPD. The disorder has become highly stigmatized as a result of this association.
