I wonder if there's any part of her that realises she has fucked up, and fucked up badly. Death, by its very nature, is so final and infinite, and maybe there's a part of her under there somewhere that realises she should have done better for Jaxon, and perhaps he'd still be here. Perhaps she realises the micro instances of mis-care amounted to a very final, horrific outcome.
But instead of owning this and being consumed by guilt and grief, she has gone into defensive mode and becoming the victim.
She really needs some professional help.
