It’s possible! Lots and lots of practice, but it’s absolutely doable. I recommend progressive muscle relaxation, since it gives you something to focus on more than just “let your mind go blank.”
This video was the tool I needed to figure out how meditation is supposed to work. Then it’s just a matter of practice afterwards.
My problem has always been that I find breathing too boring to ever manage to focus on it for any length of time.
I haaaaaate progressive muscle relaxation. They made us do it in school when I was little and I have a mental block about it. I’ve had success with guided meditations on an app called insight timer. I’ve also had success with the worry box technique. If I decide I’m not going to deal with something till another time it goes into the worry box.
