Firstly, I've discovered I have to get into a space where my mind is taken away from the worry or anguish. What I have found helpful, and you may too, is to find what will take my mind to the clearing place, where my mind can just be at peace. This could be gardening, painting, running, dancing, listening to music, anything where my mind can get in tune with what I'm doing. This, for me, automatically releases the worry, maybe not completely but for a time so I can direct my energy to something else.
