I’ve tried researching it and many explanations seem to be emotionally charged, judgmental, and non-factual. “They’re so evil and manipulative!” Okay, but can you actually describe what it is?
The the factual, non-biased explanations show what’s in the DSM-5, but it’s kind of vague. What exactly is it? What might people with BPD do to avoid abandonment? Etc.
Edit: Just wanted to thank everyone for their reply. Everyone has brought something of value and an interesting perspective.
