Thoughts?

Think I might try that as well for a release when I’m frustrated 

Thank you for your support. He is a lovely young boy and I adore him, he really is a fantastic human. 
Thank you for the reassurance, I question everything I say or do in general but more so with him as he is a literal thinker just like me and will hang onto everything I say. I don’t want to let him down. 

Thank you for your response. He for some reason as well as mentioned above for the last week been asking if it is ok to do very standard things, another example is he was carrying something today and bumped it into a door then he had to explain exactly how it happened but in huge detail. There’s at least 30 questions like this each day and like I said it’s very new but he’s driving himself into the ground with it.

I remember thinking things when I was younger and then feeling guilty like I did something wrong but I never had anyone to discuss these things with. 

Thank you Catwoman. I’ll try and see f he will give it a go.

This is just an idea, but when he gets a swear word stuck in his head, wat about suggesting that he go to the bathroom and say it outloud where there's no one to hear him?

Oh yes! Intrusive thoughts and feelings are a real soul sucker for me. It can range from re-living traumatic events to a tune or phrase that will-not-stop. For the trauma side of things, I have to change environments into something more engaging and friendly (e.g., get out of bed and get on with something [as the sleep is clearly not happening], put on some music to 'feel what needs to be felt', gaming to block it all out if I'm too tired, hug a squish mallow [or other tactile stims], shower or go for a swim, etc).
For the ear worms (tunes, phrases, etc); I verbalise them over and over, or play the tune on repeat until it's a little less 'gripping'.

I find things are more intrusive if I'm in burnout or shutdown, the downside being that I'm both over and under stimulated simultaneously (e.g. sensory overwhelm, but my brain isn't being given complex information to keep it occupied)- hence why I choose gaming for this (minimal physical effort, very stimulated brain).

I hope as he learns to understand and accept himself more (and at such a young age), hopefully he will develop healthy ways to ride the waves, and not feel tormented by his differences, but embrace them as part of who he is (this is definitely my hope for the next generation of neurodivergents).

Sometimes, thoughts can get stuck. For me, it can be like a catchy tune, it overpowers most other thoughts. Although it’s mostly about some anxious “what ifs” that control my mind, from time to time it can also be thoughts that go against my principles (so at least kind of similar to your son). It can help to think these thoughts through. That doesn’t immediately solve things but it could help to figure out where these thoughts come from. Do they stem from a subconscious emotion (maybe those words come to him because he’s angry or frustrated about something, it can be difficult to identify subtle emotions) or maybe he’s just intrigued by certain words (I was very intrigued by swear words when his age, since they felt very powerful or had a nice sound to them)? Sounds like he’s a rather black-and-white-thinker and for him, those thoughts are wrong, so it might help to know where they come from so he can take that into account when judging them. It’s certainly not wrong to be intrigued by the sound of a word or letting your head tell you its emotions in the form of words.

Your son sounds like a very good and innocent young man, I wish him and you all the best.
