Borderline Personality Disorder (BPD) is often confused with Bipolar Disorder, Major Depressive Disorder, Anxiety Disorders, PTSD/C-PTSD, ADHD, and Substance Use Disorders, due to significant symptom overlap like mood swings, impulsivity, and emotional dysregulation, but BPD involves unstable self-image and identity, unlike distinct manic/depressive episodes in bipolar or stable periods in depression. It can also share traits with other personality disorders and even have symptoms mimicking psychosis, making accurate diagnosis complex.
Overall, results suggest that having borderline personality disorder, as opposed to any particular set of criteria, increases the odds that a person may at one time or another be misdiagnosed with bipolar disorder. Misdiagnosis of borderline personality disorder as bipolar disorder has serious clinical implications.
During a BPD episode, a person may display signs such as extreme anger, paranoia, or overwhelming sadness. They might lash out emotionally or withdraw completely. Episodes can also include impulsive behaviors, such as self-harm, reckless spending, or substance use, as a way to cope with their intense feelings.

BPD Looks Like So Many Other Mental Health Conditions
People with BPD typically also meet the criteria for multiple other diagnoses, including depression, anxiety, post-traumatic stress disorder, substance use disorders, eating disorders, bipolar disorder, and so on.
Some of the symptoms of BPD are also symptoms of other conditions, which can lead to a misdiagnosis. Examples of these symptoms include impulsivity, shame, anger, feelings of emptiness, intense emotions and suicidal thoughts. Conditions that have many of the same symptoms as BPD include: Bipolar disorder.
BPD is also confused with other disorders, such as attention-deficit/hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), and other personality disorders. BPD can also share symptoms with these conditions or be comorbid with them. In particular, addictions and eating disorders co-occur with BPD.
Splitting is a thinking pattern where things feel extreme. When someone is splitting, they may see everything as all good or all bad, perfect or terrible. They may love or hate something with no in between. People with BPD, including those with quiet BPD, often struggle to see the gray area in situations.
Some common warning signs include intense and rapidly changing emotions, often triggered by seemingly minor events. Individuals with BPD may exhibit impulsive behaviors such as substance abuse, binge eating, or reckless driving.
The BPD love-hate cycle, also known as idealization and devaluation, involves rapidly shifting between intense admiration and deep dislike for someone, driven by profound fear of abandonment and emotional dysregulation, creating a push-pull pattern of closeness followed by rejection, often fueled by "splitting" (seeing people as all good or all bad). This rollercoaster of intense highs and lows leaves partners confused and can lead to chaotic, painful relationship dynamics.
Some common types of delusions that may occur in individuals with BPD include: Persecutory delusions: Believing that one is being mistreated, harassed, or conspired against by others.
How can I help myself in the longer term?
What is the BPD Stare? The BPD stare is a piercing and intense gaze that can be unsettling for others. The stare can be triggered by emotional distress, anxiety, or anger, but these intense emotions can be difficult for others to interpret or respond to.
Clinicians can be reluctant to make a diagnosis of borderline personality disorder (BPD). One reason is that BPD is a complex syndrome with symptoms that overlap many Axis I disorders.
First, people with BPD are characterized by a biological vulnerability to experience intense emotions (i.e., affective instability), which includes (a) greater reactivity to internal and external stimuli, (b) stronger emotional intensity, and (c) slower return to a baseline level of emotional arousal.
People with Borderline Personality Disorder (BPD) split as a subconscious defense mechanism to cope with overwhelming emotions, particularly fear of abandonment and intense feelings of anxiety, by viewing themselves, others, or situations in black-and-white, all-or-nothing terms (good vs. bad) instead of integrating complex, contradictory qualities. This protects them from pain by simplifying a confusing world, but it leads to rapid shifts between idealizing someone as perfect and devaluing them as terrible, often after minor perceived slights or triggers.
If you have BPD, you may experience a range of often intense negative emotions, such as:
The "3 C's of BPD" typically refer to advice for loved ones of someone with Borderline Personality Disorder, reminding them: "I didn't cause it, I can't cure it, I can't control it," to help set boundaries and avoid taking on undue responsibility for the person's actions or illness. Another set of "C's" describes core BPD traits for individuals: Clinginess (fear of abandonment), Conflict (intense relationships/moods), and Confusion (unstable self-image).
Love bombing is a term used to describe a pattern of behaviors frequently seen in people with borderline personality disorder (BPD) and narcissistic personality disorder (NPD). Borderline love bombing uses demonstrations of affection and emotion to catch and keep someone's interest.
BPD Sleep Patterns
Given all of these issues, you might still be asking, “Does BPD cause sleep problems, and if so, which types?” Individuals with BPD demonstrate higher rates of: Hypersomnia which means they sleep too much, and. Insomnia, which means they are unable to sleep enough.
If left untreated, the person suffering from BPD may find themselves involved with extravagant spending, substance abuse, binge eating, reckless driving, and indiscriminate sex, Hooper says. The reckless behavior is usually linked to the poor self-image many BPD patients struggle with.
Borderline personality disorder usually begins by early adulthood. The condition is most serious in young adulthood. Mood swings, anger and impulsiveness often get better with age. But the main issues of self-image and fear of being abandoned, as well as relationship issues, go on.
Some people engage in impulsive or reckless behaviors, such as spending sprees, unsafe sex, substance use, dangerous driving, and binge eating.
A common misdiagnosis and coexisting disorder with BPD are bipolar disorders. Both conditions have crossover traits that can be difficult to distinguish from one another. However, both disorders are conceptualised differently: BPD as a personality disorder and bipolar disorders as a brain disease.
