I rarely meditate, but I do notice that it helps. However I had an experience once when I was quietly focusing and clearing my mind and I was hit with a wave of grief for someone close who had died not long before and it just about knocked me over. That made me kind of skittish about meditating.
Slow breathing helps a lot by itself. There are many different ways of breathing to calm yourself. One that I use is inhale through your nose for about a count of 4 and exhale through slightly open lips for about a count of 8, over and over. (The exact timing is not important, do what feels natural but keep it close to those times.)
But one of the best distractions for me is to watch a TV program that I can get absorbed in, and it kind of makes me forget myself. I like detective dramas, especially British ones.
And riding my bike, very slowly and leisurely, around the neighborhood.
Yoga is too physically taxing for me. I tried Tai Chi and it too was too physically demanding. I haven't tried Qi Gong.
