Did the woman, after waking up, infer that it was morning before looking outside the window?
Was she resolved to die before waking up?
Was she surprised to discover that it was morning after waking up?
Does her occupation entail her usually not waking up during early morning?
Did she commit suicide out of guilt? If so, was this guilt related to occupational neglect?
You said that she was "suicidal due to what she saw outside", but "meant to die before looking outside the window". Would she have committed suicide that very day if she had not looked outside the window?
