I think it is very cruel to suggest that the OP is not being truthful about her daughters ear infection. Why would she lie? I have not heard of this, but i can certainly see how it would be true, but this thread reads like people are saying it is because of "issues" surrounding her parenting. There are clearly some very deep and unresolved problems going on here.
hetherine i am so very sorry about your little boy, how truly sad for you. Have you had any support for this? Even if it were many years ago?? I think you have many many things to talk about - especially that your wee lad had an undiagnosed inner ear problem: You must have so many emotions tied up in this.
Its so easy for us to say, yes, you must have her - i did so myself in an earlier post.
Sadly, i think you have not done yourself many favours with your thread, because of the wording of it - and posting in AIBU, not a good idea. Try posting in mental health section and you will get more support.
I don't have any answers for you - but my heart tells me that you should have her for christmas day but don't expect too much, you are putting yourself and your daughter under too much pressure - all this pressure for a Nigella lawson happy xmas with smiling hostess and xmas dinner listening to the queens speech - its all bullshit, most peoples xmases are fraught - you only have to look on here to see that.
I have suffered with depression, the one thing my counsellor told me that has stuck and is my mantra - i dont have to be perfect! Neitehr do you, neither does your daughter, and neither does your xmas.
She has mental health issues, so is manipulative - no mental health issues with my DD and she is manipulative and spoilt and does my head it, we dont get on for too much time - im a bit anxious about xmas day, but i want her here - it will be fine. Just don't expect the holly and the ivy - go with the flow.
Please please talk to someone, you have lots of pain that you need to deal with, for your own sake, i wonder if you can't really help your DD until you help yourself
Best wishes xx
