My primary school had to tell my Mum to buy me a bra.
I had B cup boobs at 11 still in primary - she didn't buy me a bra, she gave me a vest to wear under my shirt. Because she didn't need to wear a bra therefore I couldn't possibly need one either.
In secondary, again, teachers sent letters home explaining that as a now D cup.. i NEEDED bras.. she gave me some of her own (didnt fit, she was a 34A, i was a 38D at 13!)... she EVENTUALLY sent me to a market stall to buy a bra off some big scary looking guy..
She stopped buying food, and after some argument she would give me the child allowance and I had to go to Kwiksaves and shed meet me outside at EXACTLY 5.40 for a lift home (she was passing from work). If I was even a minute late, she'd drive off and leave me, once when she SAW me leaving the store and heading for her car she still drove away, leaving me to walk. Only a few miles but the last mile up unlit roads with no pavement.
At that point asides from my school uniform (purchased once a year, three shirts, one skirt, one blazer, never owned a school jumper or coat, and a pair of shoes) and weekly bus pass, I was expected to provide everything for myself from the child allowance - lunch money, food, toiletries, any other clothing etc.
When I got the hang of this and learned how to manage the money (although, trying to manage on not enough never works!).. she would start to do vindictive things.
Going in my food cupboard and throwing away food because 'you don't need to eat that' - stuff like honey or jam or peanut butter for sandwiches, instant noodles, bread.
She'd randomly decide certain things weren't foods 'she believed in' or that someone couldn't possibly need to eat the amount I ate (normal amounts, but she was an alcoholic living on sherry, vodka, half a slice of toast and some boiled sweets each day...).
Sometimes I'd be cooking, usually whatever time of day she wasn't in the kitchen - she'd just march in and throw the food I was cooking into the sink and run the tap over it, for reasons like 'this isn't a mealtime' or 'you don't need to eat that now' or 'we don't eat this late at night (7.30pm!)' etc.
I remember the day a social worker came to school to explain that I'd be taken to stay with a family friend, because my mother had collapsed at work and had been hospitalised - I laughed hysterically at the idea that I needed an adult to look after me, that without my mother I couldn't stay in the home - I had been looking after myself for two and a half years at that point.
I didn't actually think to tell anyone this though, I think I just thought they knew?
Looking back she got vindictive and nasty when hitting me no longer worked, because after the age of 12, when I punched her back, she realised that method wasn't an option.
I have to admit, looking back I am still angry, not so much at her - she had some serious issues she was clearly not dealing with - but at the OTHER adults who DID know things weren't right, who COULD have said something.. and did nothing.
This can't have been a generational thing for my mother, she went to a nice all girls grammar, six form and on to University in her day, so I think it was severe mental health plus alcohol abuse.
For my Dads part, he left when I was 12 and I could not live with him (actually i could have, i could NOT live with my sister!), and as she'd pushed him out and I'd had to choose to live with her... he just wasn't aware and for reasons I really can't explain, I never told him.
