This could be a pure form of bipolar disorder alone, borderline personality, atypical depression, or depression with anxiety. In short, BP II is a symptom, not a single disease. H. Akiskal at the National Institute of Mental Health has written a good deal on BP II, and would be a good person's work to look up.
