I'm almost certain my 12yr son has both autism and ADHD. I was diagnosed with ADHD at 40 and may also have ASD, but I've not been assessed.
My issue is that my son does not seem to pick up on social cues and tone of voice. Most of the time everything is everything is very literal with him.
We've been having real issues with him being very blunt and rude lately. To us, our other child, friends while playing games online, etc.
He doesn't have a big friendship network in person / at school. He's got a best friend, and everyone else is more just acquaintances - he's almost never invited over to other children's houses or birthdays, despite him considering the other acquaintances his friends (they used to be friends and have known each other all through primary and now into secondary school).
I'm worried that his lack of awareness of social cues (invading personal space, boasting without realising his boasting, repetitive phrases, loud sounds and language, saying things in an aggressive tone of voice, etc) are getting in the way of him forming friendships (sadly I can relate to his situation with friends, as I don't really and never really had many because I don't know how to get past the small random familiar chit chat phase with people). One of his "friends" (acquaintances recently told my son that his mum finds my son rude. This broke my heart because my son is often extremely polite and caring. He actively engages children and adults in conversation, but once he gets to a certain level of familiarity / comfortableness with them he can kind of lose control and things go down hill.
For example with us he'll often say something in a loud incredibly aggressive tone - simple things like 'can I have some lunch'. He does not seem to understand that this is not appropriate. He may see language and tone used in particular situations such as TV, movies, everyday life, etc and then try and emulate the tone with zero understanding and awareness of when it's actually appropriate to use that tone.
He also says inappropriate things and then when he gets called out for it or for his tone, etc he will insist he was just joking and that it was 'just a joke!' Again, he doesn't understand what a joke is and why his aren't funny.
It's exhausting trying to reason with him and tell him for the 1000th time that his 'joke' was hurtful and not funny, or just not funny at all. He doesn't seem to understand or learn why. For example we have been battling with him for the past 30 mins to go up to bed. He's just come back in to put his glasses on the table and said "I hate <name of family optician friend> because I have to wear these glasses. I hope his daughter hates him too" So obviously I've stopped him and said what he said was inappropriate, but he's tried to pass it off as "I was just joking!" again. Also just to note the glasses aren't new. And he does actually like them and actively wears them.
I'm getting very disheartened and depressed at having to worry and deal with this 30-40 times a day on top of all the other issues I'm dealing with for him. It's exhausting and embarrassing. Is there any resources such as online videos, websites, books, etc I can use to help me better understand this and how I can support him and help him realise what is and what's not appropriate in particular social situations?
