Has to be more to it, maybe other problems in her life and this was the final straw?
Can't necessarily look too good on the hospital that employed her either, patients in that hospital aren't going to be that trusting of the nurses now, one day she's there, next day she killed herself. Pure speculation obviously but there has to be some underlying issues in regards to her mental well-being and whether she should've been allowed to work as a nurse, I dunno maybe she just hid her issues well.
I'm sure the conspiracy theorists will claim that MFI silenced her or something.
