I think she's clearly had a pretty fucked up childhood, with her dad leaving her and having to be a young carer for/ the worry of her mum always being ill
But it's clearly led to her having some serious issues not least massive attention seeking behaviour. Would love to know what happened to the wheelchair btw. It's giving Munchausens maybe?
And because she's clearly not dealt with what she's been through/ learned healthy coping mechanisms as evidenced by her recent stuff (not just her mums passing but other stuff too) she is very obviously not ready to be a parent. I can imagine her being an extremely needy and emotionally manipulative mother
I think that's what's so wrong about her serious attention seeking around her mum's death. It's just not a healthy way of coping with what is obviously an extremely traumatic event.
