It's very strange that the doctors told her "There’s nothing more we can do for you. It’s never gonna get any better." Was that an irresponsible off-hand remark or what? Especially given the disorders she has, perhaps if it was severe schizophrenia or some kind of neurogenerative disorder, but autism + depression + bpd? I highly doubt that they have exposed her to all possible treatment methods, which in my opinion they should do before allowing her to take her own life.
