She was always praised by other actresses, but problem is she doesn't want praise by a colleague in a professional settings. She wanted to be their bestie, their buddy. She wanted to join some non-existent elite club of pretty, mean girls but she never got invited to it. Hence the rejection and bitterness. Point is, there never was any such secret girly society. These are all professionals. There were no slumber parties of rich, pretty girls who sit together painting each other 's toe nails and talking about how boys go weak in kness for them.
She took the word fraternity literally and felt exclusion from this sorority as a deliberate act of haughty rejection.
Hell hath no fury like an excluded sister...
