Unstable would fit that profile.
I believe they are by nature not stable.
The killer in this story is that she went to Feinstein rather than to a member of a judicial review board where it would have been investigated fairly and dispassionately.
Her claim that the event ruined her life demonstrates that she has the “its everyone’s fault but mine” attitude.
Assume for the sake of argument that her story is true, and I doubt it. She was drunk, they were drunk, nothing happened, they were laughing at a big joke, her clothes stayed on....
A stable confident person would would remember it as a crazy party that they should never have attended, be happy it went no farther and let it go as one of those things that we learn from and will never happen again.
As one who can remember a few crazy parties.....
