My mother had two completely different sides. To other people she was the fun, cool, generous mum. Other children adored her. But at home she could switch instantly into someone frightening, cruel, neglectful or abusive. She would hit me, scream, or let her "monster" side loose, and then later insist it never happened.
She also went through fast, chaotic relationships, cheated on partners, used men for money, and had arrests for violence. Growing up in that level of instability has left a huge mark on me.
I found out this year that as a child I had been diagnosed with profound autism but I believe I was traumatised.
Someone once suggested my mother might have been autistic herself also, but that feels like a get out of jail free card.
I've tried to contest the diagnosis and complain. I've been told I'm "out of time" to make a complaint because they don't look at complaints about things over 3 years old. they have agreed to look at the diagnoses again but heard nothing after 3 months.
