it takes great courage to let go, and stop dreading. what will be, will be. to focus all one's attention on just noticing, moment to moment, what is happening, what is not happening, can be the difference between spinning out and staying still.
i have found so many benefits to Mindfulness Meditation, it's hard not to recommend it to everyone. it certainly does help slow down those drain-circling thoughts. if you really want peace of mind, look where peace of mind is found.
best wishes~
