Hi
Not sure if any of my response will be helpful but I will tell what is my experience.
I am a single mother, my child has been struggling with school, highly masking just to react at home.
The diagnosis helped him to understand his own behaviour when he researched it by himself. He had no idea why he was deeply upset.
As for me, I stopped reacting and when he does stuff, I don't talk, any reaction or no reaction is still upsetting for him, but I worked out it helps him when I don't talk.
I try to talk with him when he calms down. It could take few hours or days, when he had his days to calm down, had to accept that the talking wasn't being processed anyway as he wasn't ready, he was in flight or fight response with high cortisol level most of the time.
I validated his emotions, tried REID diet which helped him a lot,I did researched PDA (pathological demand avoidance). He still had his days, but fighting with him didn't work, and trying him to understand didn't work either.
He feels always guilty to the point, that I have impression he has a split personality, there are things he does he is not aware, and fights that it wasn't him even the proof is black and white as it is nobody just me and him under one roof.
It might be helpful to validate your own feelings as it is impossible to function when you feel attacked all the time.
Try meditations twice a day, before and after you sleep.
Give to yourself lots of love and compassion. You can start envision the healing, loving light coming from your feel up to your all body.
You start being kind to yourself and you will be ready to give your child kindness and compassion as well.
My experience and looks like you have similar experience isn't understood by education experts or doctors. I studied physiotherapy, I learned about autism and had my brother diagnosed but as a parent I have different experience as to what I learned studying, therefore nobody validated my experience.
You love your child, your child is struggling, probably due to trauma and masking he has some split personality/ hidden different aspects of himself, not loving parts of himself which wasn't accepted, for example being angry for reaction for something which wasn't commonly accepted.
When we tried experts and doctors none of the tablets worked for my son and it actually made him worse to the point he was suicidal.
I did research, listen autistic podcasts as well.
Anti inflammatory diet helped him immediately, but I do not recommend drastic food change.
Being prepared for being disrespected at time it is something I prioritised over standing up for myself. That means yes he does shout and still reacts intensively but he knows that I won't react. He knows I don't react now, it was protesting before as he needed fuel for his anger but he got used to it.
Now it takes less time for him to calm down.
Now he understand things and I am able to talk with him when he calms down, being careful not to be accusing at the same time direct and telling him my boundary. I still stand for myself and having the boundary but when he is ready for it. If not then I tell him that I am not ready for interaction with him, I am still there for him when he needs to talk, but I want him to be aware that what he did needs to be expressed or dealed differently. I am trying to validate his emotions but he is just at the beginning stage at the moment, he hates himself. I will be trying to help him with loving himself or will try to find recommended therapist.
One of the issues iI struggle iss when he takes all the items without the permission but he doesn't want his items to be touched.
And his awarnes made it unconscious so he behaves as if he wouldn't do it, as if he knows with his heart (his words) that he didn't touch it.
Not easy to talk when he isn't consciously aware, when he thinks it isnt right, so doing it and not consciously remembering it as if it would be different person.
I think it is all what the drama is from.
It is from self hate, from splitting personality, not loving all the parts of himself.
I only learned from other people experiences, definitely not from the experts. And Pda is on the scale and is part of autism, sometimes invisible die high masking outside.
I feel you and I am sending you love as you deserve it.
