All personality disorder presentations share common features. These can include difficulties with:
A - Affect - such as suffering from negative feelings and big overwhelming emotions
I - Identity - such as feeling confused and unsure about yourself and what you want in life
R - Relationships - such as experiencing ongoing relationship conflicts with others
The most commonly diagnosed personality disorder is Borderline Personality Disorder (BPD). This is diagnosed when a person has most (at least 5) of the following challenges:
- Fears of abandonment or being left alone.
- Unstable or intense relationships that are short-lived
- Feeling like you don't know yourself, who you are, or what you really want.
- Having problems managing impulsive behaviours that are harmful, such as drug and alcohol abuse, binge eating, driving too fast, overspending, or getting into unsafe sexual situations
- Feeling suicidal or regularly self-harming
- Being troubled by intense moodiness, irritability or anxiety
- Feeling chronically empty inside like you feel like a nobody or nothing
- Finding yourself often getting intensely angry or loosing control of your temper
- Feeling very suspicious or feeling out of touch with reality, like feeling paranoid about others, or feeling very spaced out or dissociated
As can be seen in the diagnostic criteria, BPD is a combination of difficulties in managing intense affect, experiencing a stable sense of identity, and maintaining satisfying long-term interpersonal relationships. There is substantial variability in how people display their underlying confusion with how to be in the world and how to be with other people.
Personality disorder ranges from mild to moderate to severe. Severity often fluctuates depending on whether there are real or perceived triggers or threats to safety in a person’s environment or interpersonal relationships.
