The problem here is not what words you are using. Does she have a therapist,a psychiatrist,medications? It sounds like her meds are wrong or she is having pretty severe episodes. Is she bp1 or bp2? Is she using drugs or alcohol? Why is she acting out like this? Maybe she should be hospitalized until they stabilize her.
