i think my best friend might be schizophrenic - what do i do?
my friend has been having paranoid delusions (in my opinion, not hers, and she is unaware of my opinion) for several years. on a psychiatrist friend's advice, a couple of years ago i told her i was worried about her and gently requested she see another therapist (as her own, she said, fully bought into the [in my opinion] delusions). she assured me there was no need - i didn't know what else to do.
fast forward to this week, when she told me about several incidents that recently occurred with total strangers - about four people she has never met before volunteered info to her, about her, that they couldn't have known - well, not plausibly, anyway. and i am remembering now that these are not the first instances of this kind, and up until now, i thought she was making them up to convince me that her beliefs are true [because while i have not told her i think she is delusional, i have conveyed skepticism about her beliefs.]
but yesterday it occurred to me that she might not be making instances like this up - she might be hallucinating.
what should/can i do?
