The OP doesn't want help. Whether that's because of poor mental health, denial, or other reasons, she wants to carry on as she is. And we cannot make her accept help or push her to action. Which is frustrating but true.
When posters (me among them!) said how shocked they were at the GPs failure in her duty of care, some days ago now, the OP defended her GP strongly. So I was very surprised to see the about turn turn yesterday. Which I assume was because posters were getting frustrated and questioning how this could be happening.
I think the OP is desperate for attention and comfort, and is taking the support and advice on here to satisfy her needs without wanting to take advice or make any changes.
I won't claim to understand the red herring that is the tax assessment. What I do see is that the OP is perceiving her mothers actions as very threatening, although from the outside I really can't see anything ominous about asking for employment history or P60s etc.
Whatever the reality there, it's allowed the OP to get attention without having to do anything, for a while longer. She wants comfort and affection and is saying anything to keep getting that.
Personally I'm finding the apologies to an unborn baby posted on the Internet rather unusual. And writing to strangers on the Internet as a way of talking to a baby, as an alternative to actual health care or bonding with the baby in real life, it's uncomfortable to read. No one in this whole situation seems to be interested in the baby's health or development - even the health care professionals.
It's all very sad, confused and I hope, whatever the OP is seeking and getting from this thread, it helps her in some way in her own life, whatever is going on.
