ILik it's a huge topic and would vary enormously from person to person. But at 8 I was frequently sitting on my bedroom windowsill wondering about falling out, so I do know what being eight with terrible self esteem feels like - and that is despite having had the most incredibly supportive parents. The best things I've found have been
shared experience - knowing that there are other people who have the same issues, and liking them, finding them funny and insightful and witty and clever, and knowing that the name for what we share is autistic spectrum disorder, that's been a massive thing. It takes the sting out of the feeling of failure. I'm trying to think of a NT or universal equivalent - I suppose like coming out of the loo with loo roll stuck to your shoe and someone else saying "I've done that!" and feeling rueful instead of mortified.
Following on from that looking at strengths - yes I have a lot of deficits and the diagnostic process obviously focuses on deficits, but we also have some fantastic strengths. Attention to detail, immersion in tasks, passion, loyalty, solution-focused - and finding that I had THAT in common with other autistic people as well as a propensity to forget about the washing-up was very validating.
Maybe try Autistic Pride with him? Do you have any adult autistic friends?
colours for emotions - like a lot of people on the spectrum I really struggle to name emotions or describe them. That doesn't mean I don't feel them, I feel emotions strongly. I just can't always say what type of sad I feel (is it frustration or sorrow? Is there a meaningful difference?) so I tend to go from zero to self-loathing without the steps between. Rather than extra pressure to describe the emotion, using colours is a way to communicate how I"m feeling before it gets too bad.
using text - I'm very articulate on the internet
where I don't have to keep up with the demands of in-person processing
realising I don't have to meet NT expectations - I suppose goes alongside the first two. It's that old thing about judging a fish by its ability to climb a tree. There's a good blog post on that here autisticmotherland.com/2018/01/31/looking-back-and-thinking-forward/
There are probably more. I'll have a think....
