Not that it is not possible,but the several incidents/behaviours mentioned,sound more like several disorders,not just bipolar,and some things mentioned do not sound like bipolar.
If possible,see if you can get a different pdoc's opinion/evaluation. Several meds may be needed,not just mood stabilizers,but maybe even anti-psychotics too.
This definately is not going to be cured or stabilized by some natural/holistics/herbs to name a few,real professional help is needed.
I seriously feel she needs help,and needs it asap.
I wish you luck with this.
