Drinking is how she tempers her down time.
In her up time, she’s fashions herself as Saul Alinski, THEE standard barer!
There isn’t much if any underlying personality, just strategy, and relentless strategy...fake it to make it.
She can’t have down time unmedicated, the better angels creep in, she questions her strategies, her common interaction...she knows she’s flawed.
Sit in the dark to reduce all input, relive the day, plot tomorrow...all while drinking. => seen it!
I realize this all sounds insane. But, I know a covert narcassist very well.
Narcissist, not narcassist.
Not so covert
I would make it simpler...she is a flat out alcoholic....selfish, self centered, driven by a hundred forms of fear
