@Justme02 can I firstly say it most definitely isn’t just you.
Our dd is also severely autistic with SLD - she is 26 now - although she is more like a 3-4 yr old in most aspects and she does have limited speech. We suffered many similar types of problems when our dd was much younger. Throwing and smashing tv’s was a particular favourite amongst many other destructive tendencies! 🙄
She cost us a small fortune but, more importantly, the stress and worry of keeping her safe was horrendous.
I’m not sure how old your DS is but can I say it does get easier as they grow older as they do seem to calm and mature a little although still far from problem free. It angers me to hear that nothing has changed in over 20 years! We were the same! No advice or help from anywhere! 😡
My dd finally went to an excellent residential school - none of the specialist day schools could cope with her 😢 - and although it was devastating initially, it proved to be an absolute Godsend for her as she learned so much from the environment she was in although I appreciate this is more of a long term suggestion and could well be something you don’t wish to consider.
Another more immediate thought is whether anyone has suggested your son be prescribed a mild dose of anti psychotic medication? I know it sounds pretty horrifying but this was only suggested to us when our dd reached adulthood. We agreed to give it a go and, in all honesty, it has proved an absolute revelation. She has drastically reduced her obsessive behaviours and rarely displays meltdowns nowadays. (Thankfully she is not too destructive these days.
)
I so wish I could suggest something more practical but, if your DS is anything like our dd, he will find a way around things. Of course they are worth a try but if it was me I would certainly be investigating medical and educational help. Also, does your DS have epilepsy? Our dd does and we discovered many of the anti epileptic meds can cause destructive/disruptive behaviours. Again, something else I would get checked if your son also suffers with seizures.
I do wish you the very best of luck!
. Nobody knows just how bad it is until they have been there and living with it 24/7. (Apologies for the long post.)
Also, just to add, there IS light at the end of this awful tunnel! Our dd lives in her own gorgeous apartment within a small complex for young people with SLD on supported living basis. She is close to home now and we have an amazing relationship with her. NEVER thought we would get her anywhere near how she is now.
