Is it BPD or just mood swings?

Everyone has moods; borderline patterns are different in speed, trigger, and cost. BPD-type shifts are fast (minutes to hours, not weeks), fired by relationship events — especially anything that smells like abandonment — and severe enough to torch plans, jobs, and bonds. Only a clinician can diagnose; a pattern this costly deserves one.

Why the distinction matters for you

Mood swings ask for patience. A borderline-range pattern asks for structure: clear limits, predictable responses, and encouragement toward treatment (DBT works). Getting the frame right protects both of you from the drowning-rescuer dynamic.
