Signs and symptoms of bipolar personality disorder may include:
Extreme emotional swings. Unstable emotions and moods are common with BPD. One moment, you may feel happy, and the next, despondent. Little things that other people brush off can send you into an emotional tailspin.
Chronic feelings of emptiness. People with BPD often talk about feeling empty, as if there’s a hole or a void inside them. At the extreme, you may feel as if you’re “nothing” or “nobody.” This feeling is uncomfortable, so you may try to fill the void with things like drugs, food, or sex. But nothing feels truly satisfying.
Unclear or shifting self-image. When you have BPD, your sense of self is typically unstable. Sometimes you may feel good about yourself, but other times you hate yourself, or even view yourself as evil.
Feeling paranoid, suspicious, or out of touch with reality. People with BPD often struggle with paranoia or suspicious thoughts about others’ motives.
