One of the techniques I learned was to take deep breathes for about 30 seconds, focusing solely on breathing in and out. Everytime a thought enters your mind, make it leave. Next picture a scene in your mind, while you continue your deep breathing, that makes you very happy. Focus intently how you felt while you were there.
Maybe it was the day your husband asked you to marry him. Maybe it was the day you got your first puppy dog. Maybe it was the day you brought home your first child. Maybe it's a favorite place, the ocean, the mountains, the desert.
Picture the scene and how you felt for at least 30 seconds.
I haven't tried it enough to know if how well it works, but I say it's worth a try. ;-) Why not try it right now? ;-)
Stress is incredibly bad for you. Let it go. I know I'm trying.
