Kind of depends. When I feel the following it's definitely my bpd:

A pattern of unstable and intense interpersonal relationships characterized by alternating between extremes of idealization and devaluation

Unstable self-image

Recurrent suicidal behavior, gestures, or threats, or self-mutilating behavior

Chronic feelings of emptiness

Transient, stress-related paranoid thoughts

I've deleted the bpd characteristics that don't fit me.

The symptoms that overlap I put down to bp. But hey that's just me.
