There's definitely a "get over it" for dread and it's called stoicism (not an expert). Sometimes you have to do things whether you like it or not just to survive and "getting over it" will prevent you from dying.
Trying to just "get over it" with the neurodivergence example noticed is the kind of thing likely to result in a panic attack or other uncontrollable expression of emotion. It's not something you can change just by wanting it hard enough.
Thanks, I’m cured
come on man telling someone with autism to learn stoicism and just got care
Even if this was true for neurotypicals (which it isn't) it wouldn't be true for neurodivergent folk.
Can you hold a conversation next to a lawnmower? A jackhammer? A jet engine? At some point there's literally too much noise for you to communicate verbally anymore. That point is different for different people.
