I do understand what you're saying,Maggie.
I've studied how June would have felt too at not being able to conceive and the impact that would have had on her mental state. Actually being told to any woman is devastating and its effects can have an everlasting effect especially and probably more so when there's a business to consider,heirs.
We don't know how June took the tragic news but it reflected in her ability to cope and accept her problem which further came to light when Sheila was only eight months old when June had to be treated in hospital which led to her admission as an in-patient for a spell.
I wonder if June had ever wished that she'd bore/borne Sheila herself,that her inability to conceive would have come to the fore aggravating her thoughts.June may have blamed herself,or as her mother used to say " the devil at work ".
Over time and because of June's delicate state of mental health,another visit to the hospital was called for and a second ECT administered to try and improve her mind and block out all past thoughts which were taking over her mind. June was quite a sick person to have had such treatment. I used to think it was a cruel treatment,but the patients who underwent it were pretty unwell.
If anyone should have known about Sheila's moods and behaviour it should have been June having suffered depression herself.
I have lived it Lookout and I don't believe June necessarily though any of that.
I believe Sheila was ill either because she was genetically programmed that way or because her trauma before she got to WHF was profound enough to have caused her to be unable to bond deeply with June or any other primary carer. There certainly was conflict, I would imagine Sheila was probably a conundrum to June as much because of the way the world had changed since June's upbringing as much anything else. June was said to be very strong minded or controlling, depending on how you look at it and there was bound to be difficulties.
It is quite probable that Sheila had a genetic tendency towards schizophrenia which was exacerbated by her adoption and difficulties to bond properly with June but I don't really know, it's all just speculation. I cannot believe that June didn't love Sheila however much 'at sea' she may have been when trying to deal with her. Natural children are not always carbon copies of their parents, one can be like great, great uncle somebody who burned the local church down or whatever. Think all parents hope for the best but they don't always get it and most people muddle through. Sheila's illness definitely would have made relationships very difficult for her.
I agree that June seemed to be ill equipped to deal with children whether natural or adopted due to her own difficulties but I still feel she is harshly treated because of her own mental health problems, she definitely didn't kill anyone and had a dreadful death imo and yet at times she seems to be blamed for the whole catastrophic disaster. I have no idea what June was like as a person but I feel for her, maybe I'm biased because she's a fellow adoptive mother and I make no apologies for this.
