That does sound like it could be a tic disorder/tourettes. They can sometimes hold it in but if she is suppressing it at school it will come out like this afterwards.
Does she have autusm diagnosis, have you had support re potential pda. My son is almost 10 diagnosed autistic pda and with tourettes and profound sensory processing.
The most helpful things havd been an Ed psych who got it and wrote a brilliant report which has led to support and an OT assessment.
Plus seeing Neurology and finally getting tourettes diagnosis. But its been a long road to get to this point.
When was she last asessmeed, does she have an ehcp?
There are strategies you can try if pda look at pda society. But really school need to helping reducd the overwhelm.
Is it the push from slamming doors? Thats a different sensory input from hitting things.. the feedback she gets will be different. Same re wearing, shouting etc. Slamming, stamping etc.
Am just wondering what advice you have had and what your options might be for support going forward.
In my area we have early help and family support which would be your first port of call. They may not be particularly helpful or understanding though.
Tourettes action have some good free resources etc that are worth looking at. If you can video some of the tic like episodes.
Don't tell her not to swear, just ignore it.
What works best for de escalation? For us its space, quiet, everyone else out the way. But you have to ride it out.
Its so hard, but please dont worry re eviction. That wont happen.
