I've been told many times that I should practice meditation to help with anxiety. I find some guided meditations helpful (focusing on breathing and relaxing images or self-compassion, or whatnot), and I like progressive muscle relaxation (where you go through and tighten and then release different muscle groups in turn). But actually meditating in the sense of quieting the mind tends to go nowhere. I just jump into puzzling something out or rehearsing a conversation or something almost instantly. Almost as soon as I've noticed that I'm thinking and tried to come back to focus on my breath, I'm off again.
I've tried concentrating on my breathing, thinking "here..., now..." as I breathe, incorporating movement (I just seem to get fixated on the way I'm moving and how it matches up with my breathing or not) and making an Om type noise on the out-breath, but nothing seems to help much.
Has anyone else tried meditating, and what techniques have worked to help you clear your mind/stay with your breath/etc.?
