Not trying to get you to try again, but I used to feel that way about meditation until someone pointed out the goal was not to be empty and not have thought. When you have a thought you just observe it and make note of it and go back to your breath or experience or body scan. Sometimes you will just have a billion thoughts and you can’t get past that. Other times, and the more you have a practice, this gets easier. Ultimately it’s not about meditation but being mindful as you go about your life, and that’s what you’re ultimately practicing when you are meditating. Good luck!
