You might find it easier in primarily neurodivergent communities. In my experience, Mastodon has a lot of neurodivergent people - there are (at least) two servers especially for us, neurodifferent.me and autistics.life.

Also, don't use AI - it sounds wrong and bland. For me, I tend to adopt the writing style of what I've been reading recently (it's most notable when I pause what I'm writing and come back to it after reading something from the 1800s) so I might recommend reading it for a while to get your brain in that mode and then maybe posting, if you also do that.

Best of luck!
