@DemBonesDemBones - you are so very far off track here. I didn't go into detail on my last post because I'd already outlined our circumstances on my previous post.
But for your benefit:
I have 13 yr old twins. Both are autistic/ADHD - plus a whole list of other diagnoses.
I myself am autistic and ADHD.
So I appreciate your passionate defence of the OP but I was being gentle with my language. I have dealt with everything the OP describes and more. I experience neurodivergence as both a parent and as a neurodivergent individual.
To put things in perspective, my son is 13 years old and still in nappies. We have been at A&E and hospital over the years as he has self-harmed and really badly hurt himself. He has bitten my all over my body, some of the bites were so bad they were infected.
Oh, and I should mention that DD is PDA too. Because that's also a bundle of fun.
DD went to mainstream with a bit of support. She wasn't diagnosed until she was 10 and then we found that she had very significant difficulties - such as being approximately 5-6 years behind with her receptive language that NO ONE had picked up (until I sat in the SENCO's office and refused to move until they agreed to refer her).
Over the years, DD learnt that she came second place. Because her twin brother's behaviour was so challenging and so all-encompassing. I feel fucking terrible about it. And of course there are long-term consequences. When she got her diagnosis and I realised that she had been struggling with the same things as her brother had but no one knew, and no one helped her, I cried my soul out.
So please, don't lecture me. My whole fucking life has centred on autism, ADHD, and everything that comes with it - both as a child with it myself, and now as a parent.
You know what I have to do? I work most nights until about 5 or 6am because I have to pay the bills. And then I'm up again with the DC a couple of hours later. I am so fucking chronically sleep deprived I don't even know how I'm still standing. I'm self employed. I'm up and down with the DC until about 3 or 4am because DD doesn't sleep and DS needs 24/7 supervision. I had to leave my comfortable, well-paid job to care for two babies with SEN (because my partner fucked off when I was pregnant). I home educate now because there are no schools that are suitable any more (DS was in special school anyway). And I work full time in my self-employed role but I have no money to pay the bills. I don't know when I last did something for me. I'm constantly late with my work and losing clients because of the needs of my children. So yes, I'm well aware that the SEN family revolves around the child's needs.
When I said I knew it was hard, it was from first-hand experience.
And yet, I still think the OP needs a bit of help "reading" her son. I went on three separate parenting courses - each one about 8 weeks long (half day per week with homework). And fuck me, it opened my eyes. I suddenly understood more about my child, and actually also myself. The neurotypical parents on the course with me learnt even more than I did. I have the benefit of first-hand experience of being neurodivergent.
OP has said that her DS doesn't have sensory needs because he hasn't told her. She called his meltdowns "tantrums". And despite describing horrifically severe behaviour, there is no EHCP in place as it was only applied for recently, and no meds. OP has been fighting with all her might but she's battling against the current.
Her son needs help and support. He's screaming out that he's in crisis. Yes, OP and the younger sibling need protection and support too - but this whole family needs help. And sometimes that means being honest enough with yourself to consider whether you could be managing things better. A low-demand parenting approach is often successful - has the OP tried that? It doesn't sound like it. And that's not a criticism. At all.
As I said in my last post, the ND child themselves often end up hating themselves and thinking that no one wants them. Self harm is common among ND teens.
This isn't just about stopping dangerous behaviour NOW - it's also about putting mechanisms in place that will support them all in the future. And that means being brutally honest with yourself about whether as a parent, you could be doing better too.
Just giving the OP ass pats and telling her how hard it is won't help. She needs practical solutions and suggestions for when she's ready to think about things. But as I also said in my first post, her DS desperately needs meds. When ADHD symptoms are that severe, it's absolutely awful for the person suffering them - her DS is overwhelmed and struggling.
