Is she auditioning for a Real Housewives show? Because that's the type of person she sounds like.

I agree, don't listen or worry about her. She's a vampire. Taking, taking, taking, but not giving. "me me me, the spotlight is on me!" Whatever. Let her play her game but don't let her get to you. The less energy you give her, the more unsatisfied and unhappy she will get. The ultimate distruction for those people is to be ignored and forgotten.
