Stop trying to have an empty mind. That doesn’t usually work. At least not for me as an autistic person who also has intrusive thoughts. I’ve found it’s easier to get into the meditation. If you can instead. Allow yourself to focus on an aspect of it. Such as a visualization if you’re able or a thought that interests you that connects with the meditation or outcome. Such as if trying to ground or calm yourself. For example. Allow a song to be your focus in your mind that relaxes you. Or something else. Or what not. Focus on your body…such as your breathing. While trying to go into it.
