My impression from the documentary was that one of the girls was a no-shit hallucinating/hearing voices schizophrenic (just like her father). The other had more standard or common depression-type issues. Like Harris and Klebold. One has the real crazy and one has the intense emotions.

It fucking sucked and South Park is over. I watched this the day after I finally psyched myself up to watch "With Bob And David" and now I'm ready for suicide.
