Wow, that sounds really, really tough!
Does anything work? Anything at all? Because right now, I would not give a second thought to bad habits or anything at all like that and just do whatever helps. And call your mum again. And anyone else who can help.
If she sleeps in the wrap, can you put her down, or does she have to stay on you? If she likes wraps, you could try a woven and do a kangaroo carry, then you can put her down more easily once she's out - that's if she'll let you do that at all.
