She seriously seems like she has Borderline Personality Disorder. My sister has it, and so much of the behaviour is the same. Lying, constant ego boosting, not having humility, grandiosity, huge emotional blow outs. It’s draining just following her on social media (where people try to present the “best” representation of themselves)… imagine what it’s like to know her in real life?
BTW this is no judgement on people with BPD. I have huge empathy for anybody dealing with a mental illness or personality disorder. But this woman needs help. Take away her passwords please!
