Apparently she was greatly struggling with turning 30 as she saw it as old from what her writings have revealed. And she certainly had issues about how she looked from the beauty competitions since she started throughout... often common in the industry she had aligned herself with.
The last place people with a weak self-image should be is the entertainment/Hollywood/modeling type careers. It will take their life and sanity one way or another.
She looked better and fitter than the vast majority of the people in the USA. I guess there is always somebody younger and better looking to compete with you in the looks sweepstakes, though. Associating with the toxic BLM gang would keep anyone angry, anxious and in a negative frame of mind too.
