My trauma and depression were caused by events at school, like my sexual assault aged eight, experiencing female puberty whilst autistic, and trying to live in a world set up for neurotypical people whilst autistic. Home was physically safe for me. Yet I just wanted to stay as far from my family as possible, like OP's DD. I blamed them for everything that was going wrong for me when I wasn't blaming myself, like OP's DD. Like the DD, I struggle to maintain friendships. Like the DD, I prefer solitude.
Once the OP had clarified that she had worded her opener in a way that many posters had misunderstood, I didn't attack her again but instead suggested autism as a possible cause for DD's behaviour. Making suggestions is what autistic people view as helpful. Did you notice that change in my posts? Sure, I also replied to rebutt what other's were saying, but that wasn't aimed at the OP.
I'll go back to the bit about preferring solitude and the comments the OP made about taking DD on holiday, because this is an example of how autism coupled with an environment set up neurotypicals can drive hostile behaviour in an autistic child.
When you're autistic, if the people who control your life to the point that they decide if and when you even eat take you to somewhere that:
- is out of your routine that involves having to pack and worry about forgetting things and travelling to get there,
- is probably loud and bright and crowded and certainly unfamiliar
- is probably too hot
- requires you to share a room with other people and lose your solitude for two weeks
But:
- those people are telling you that this is expensive and a treat and you are lucky to be going
- you don't understand your own feelings about this other than "bad"
- you've been extensively taught not to express ingratitude, that you say thank you and smile even if you hate the gift
How are you going to react to this? I'll tell you how.
The SEND kids boards is full of parents of low-masking autistic kids bemoaning the fact that they can't go anywhere without DC(9) having a meltdown, because low-masking kids can't mask how they feel about going somewhere that causes sensory overload or other forms of distress. High-masking autistic kids will mask and mask and pretend to enjoy being there as part of the masking, because they want to appease the people who control every aspect of their lives, until they can't mask any more. And when they melt down, they cannot articulate the bad feeling but they know who caused it by taking them on holiday: their parents. The child cannot articulate why they are unhappy when asked because that involves telling the people who control everything including whether the child eats or not that the "treat" was anything but. If they do say that they didn't enjoy the holidat, they are branded "ungrateful", even though for a lot of autistic children, lego in their shoes every day would be more pleasant than spending two weeks at Disney.
My own experience was that, as I approached the point at which I was able to leave home, I became more and more impatient to do so because I could see the ability to control my environment tantalisingly just out of reach. And I acted a lot like OP has described her DD as being like.
