I've tried in the past and mostly nothing happened. I still have my usual thoughts racing around my mind. One time though, it was like a switch had been turned off and I was terrified! The thoughts stopped and I scrambled to get them back in panic. I really hated the sensation.
All the articles I have read seem to say that meditation is of benefit to neurodiverse people. Maybe if I'd have pushed through the fear, it would have got better.
Have you had any success with meditation?
