Hi JL, and welcome
Bipolar and Borderline Personality Disorder are two different things.
However, there can be similar behaviors, a person can have both BP and BPD (co-morbid), BPD can be misdiagnosed as BP, and lastly the communication tools here on our BPD support board can help reduce conflict with others. That's whether they have BP, BPD, or not.
This might help:
COMPARISON: BiPolar Disorder vs BPDA few of our members have BPD, but are here for support in dealing with loved ones who have BPD. Some of us have BPD traits (I may have a few), but not at a clinical level. A lot of us deal with Depression or Anxiety of PTSD, and some might be Bipolar.
That focus of the board: the discussions and learning materials, are about BPD, however.
Take a look at the link. If you think you might fit here and the discussions, materials and lessons might be of help, we'd love to hear more on how best we can support you!
