Truly deep depression involving a psychotic break, as can happen during postpartum depression, is terrifying. Depression runs in my family. One of my female relatives actually tried to commit suicide, at home, during a postpartum period, a few months after giving birth to her 3rd child, when she also had two older toddlers in the house, along with the baby.
None of the children were harmed. The suicide attempt was interrupted, and she was briefly institutionalized. But… the whole thing? Really terrifying.
