For some people, your awareness of worry comes in the form of feeling compelled to distract your mind, feeling vaguely off, or constant movement - tapping or clicking your pen, biting your nails, bouncing your knee, popping up and down but never sitting still long. And a discomfort with being in silence.
Ask yourself, what drives these behaviors, what prevents you from being comfortable with long silence? Or, even if you are comfortable in silence and stillness, does your mind become quiet, or does it rage on? And what percentage of your thoughts are positive, loving, uplifting, fun? Compared to what percentage of your thoughts are self-deprecating, replaying negative interpretations of experience, worrying, playing the "what if [x (undesirable thing)] happens" game?
Your mind is a powerful and wonderful tool - can you learn to use it to work for you instead of against you, can you cultivate easy focus, easy calming?
