G.

My guess. 

She’s got a character trait anyway. High maintenance and high volume. Probably a borderline personality disorder.

She feels less loved than Jamie. And now there’s a new sibling coming along. She could slip even further down the totem pole.

Mum tries to love her. Dad just tolerates her and tells her to get in line, or else.

The step parents? Well I do my best to be nice to her and not be harsh or tough, within reason. My sanity is more important. 

Interestingly, she doesn’t like me. Probably because I let her know that her style doesn’t work with me. It disempowers her.

The other one? Ella. I’ve never met her but I’m guessing that she’s somewhat less tolerant than I.
The Little Girl, she’s seeking love and attention and making it worse at the same time. 

She’s already, at the age of seven, aware of the fact that she’s in the grip of an addiction.

She knows that her attention seeking behaviour, that which she can’t control, is making her unliked.

She needs help. Proper help.
