That is because the level of her triggers is too high. There are too many anxiety provoking events. It may not feel like it to you, I understand, my life is utterly centred around my kids needs and it is very very stressful.
However this very extreme aggression is a sign that her world is way too difficult for her at the moment, and until you make her life easier it won’t get better, and one day you will have a big strong DD.
I have to even watch what I say to my DS, he has so many routines and that is his anchor. I have to have so much patience I feel I’m going to explode some days.
But once their environment is much easier and less stressful for your DD and your DS, then you really can start to very very gradually expose them to more and more. My DS can now go anywhere with me, but it’s taken months and years of gradual getting him used to stuff.
Take shopping. I stopped going shopping. DS would have meltdowns if I didn’t do a certain thing etc. or the lights. Or the noise. You know what? I really didn’t have to go shopping. I ordered everything online. It’s so cheap to do that nowadays. But I took my kids to the shop just to get him used to it, and I used to just go for 2 minutes, just once or twice a week, and always get a treat at the end. If I stopped having to actually shop for food, I could focus on just helping the kids get used to it.
Now? I can go shopping anytime it’s fine.
So school? It’s not working... What can you do? You can
- take DD out of school and home school even temporarily.
- you can ask for reduced hours at school or days
- you can talk to the teachers and find out more
- you can phone social services, women’s aid, go to your GP and explain and get as much help as you can.
You also need to protect DS as a priority too.
I think the frustration can be, you are cross and angry yourself too, about your past relationships, about how hard your situation is, about DD and can unconsciously expect way too much of DD and see her behaviour as having nothing to do with your relationship with her either. I know that’s blunt but anyone with a challenging situation will often find it also difficult to cope, as you’ve clearly said in your post, and that will pass on to our kids so is a warning sign to you also - you might be starting to project a lot of anger onto DD?
But you’ve got a will to act now, so put everything else on hold and do just contact everyone professionally.
