Hi Verity,
thank you for the diligent description, you are a very observant analyst!
From her own words "I wont know what to do
I wont have control
I wont be able to look after myself and survive
I am afraid to be uncomfortable and suffer a lack of resources"
we read that her old brain is activated here, and this obviously are beliefs she adopted from her parents - so even these are something she hasn't yet processed enough to be able to let go, in terms of the colon. They are also in the way for her to stand up for her boundaries, and therefore they need to be reviewed.

Then obviously, her bouts of aggression reflect a cortex constellation, as Ousaima already mentioned - the one on the level of "function and role in the group", about territorial anger and identity (we didn't talk about these constellations in particular yet, but this is a great example). Her fear of her father made her suppress the anger she felt underneath, so it comes out later in an uncontrolled way that's also frightening her and triggering feelings of guilt. This would certainly need self-forgiveness and a way to express aggression in a safe way - through art, voice or theatre for example which wants some space in her life - or even exercise, dance or martial arts?

Her bingeing makes me think of another related issue, and that's disgust/resistance which plays out in the energy distribution, the pancreas hormones insulin and glucagon!. She felt such a resistance towards her partner when he let her down and brought in his kids into the house. She might also trigger these feelings about herself, in her helpless guilt carrying the "curse" of anger and aggression.
So having her confirm that would give us the strategy how to make peace possible and resolve the pattern.
