BPD is often misdiagnosed as Bipolar Disorder, Major Depressive Disorder, Anxiety Disorders, PTSD/C-PTSD, ADHD, or other personality disorders due to overlapping symptoms like mood swings, emotional instability, and impulsivity, but BPD's intense reactions are typically triggered by interpersonal events, unlike bipolar episodes which last longer. Complex PTSD, anxiety, and depression are common comorbidities, further complicating diagnosis.

Symptoms
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 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.
Borderline personality disorder often co-occurs with other mental and physical conditions. These can include mood disorders like depression and bipolar disorder, externalizing disorders like conduct problems and attention-deficit/hyperactivity disorder, and metabolic-related disorders like diabetes and obesity.

Partners and family members of people with BPD often describe the relationship as an emotional roller coaster with no end in sight. You may feel like you're at the mercy of your loved one's BPD symptoms—trapped unless you leave the relationship or the person takes steps to get treatment.
Splitting is triggered by anything that causes a person with BPD to take an extreme emotional viewpoint. The triggers are similar to those seen with NPD and could be something that seems harmless or “innocent” but is enough to spur emotions that a person with BPD is not able to handle.
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.
The “3 C's” often used in understanding BPD are: Clinginess (fear of abandonment), Conflict (intense relationships and mood swings), and Confusion (unstable self-image and identity).
Up to 50% of people with Borderline Personality Disorder (BPD) experience psychotic symptoms like hallucinations and paranoid thoughts. BPD-related psychosis typically differs from other psychotic disorders as symptoms are usually brief, stress-triggered, and the person often maintains some reality testing.
