It's pretty normal to have some shaky times before stabilizing when it comes to psychiatric treatment. I hope she continues her treatment, I am sure in the end she'll get out of there much better.
And the part about her "even being able to make fun of herself again" is stupid. People really expect her to come out of such a traumatizing experience and go to SNL, per example, to mock her own misery just for some laughs? ugh......
