The diagnosis of a personality disorder must be done carefully. The symptoms need to have lasted for long periods and be stable. Before you accept a diagnosis of BPD, make sure that any other mental illness is treated first (depression, an eating disorder, a substance use disorder, etc.).
It is hard for people with BPD to control their emotions and behaviour.
A youth or young adult with BPD may:
- have intense feelings such as sadness, worry or anger
- act on impulse or seem aggressive
- try to harm themselves, or act in ways that can hurt others (drive dangerously, binge-eat, self-injure, misuse drugs or alcohol)
- avoid social situations or getting involved
- worry about being embarrassed, criticized, rejected or abandoned
- have feelings of self-hatred, an unstable sense of self or no self-confidence
- feel misunderstood and not have a good sense of who they are
Day-to-day life can be very challenging for someone with borderline personality disorder. They can have trouble controlling their emotions, so it can be hard to have healthy relationships. The symptoms can make it difficult to deal with everyday life like school, work or at social events. It can be hard to know how someone with BPD will react to small problems and the pressures of everyday life.
BPD is difficult to diagnose because the symptoms of other mental illnesses are similar. BPD can also look like other personality disorders. That is why it’s important to be assessed by a trained person like a psychiatrist or psychologist over a period of time. If a youth or young adult has another mental illness such as depression, anxiety or an eating disorder, they shouldn’t receive a diagnosis of BPD until the other mental illness has been treated.
