I have a large amount of compassion for this woman. I can imagine feeling like her... the hopelessness and desolation that is completely overwhelming borne from sleep deprivation, disconnection, abandonment. I can imagine the son, locked in his body, reaching out through screaming and howling, frail yet strong, unpredictable and relentless. Glimmers of connection and love but too few amongst the drudgery, the noise, the loneliness.
I think it’s very understandable and without being met with compassion, makes reaching out for help even harder.
To think the unthinkable, and then to say it out loud - without this outlet, without understanding , without being met with resources and support, it is not to hard to imagine how it seeps into tragic action.
