I see that she says she was kicked out of her home when she was 16 and placed in a mental health facility[1]. But this is not the same as having a mental illness. Certainly it's been the case before that a perfectly healthful individual has ended up in such an institution. Especially people suffering from emotional trauma that they are unable to handle on their own.
