I know worrying serves no purpose and just takes time from the present, and I am constantly trying to modify this useless behaviour, but more often than not I slip back into 'worry mode'.
I have a mantra which usually helps - 'What will be will be' - I know a bit 'Doris Day', but there's nothing wrong with that. Today that mantra has been repeated over and over, and I am now in a place where I can relax. Stroking Cuddy and the cats always helps too.
I think my worrying in general comes from a place of frustration, a place where I cannot control or even have any effect on what's going on. I am not a complete control freak, but really dislike it when something may happen that I cannot influence to the better. But for now I am giving it over to the universe to manage for me. after all 'What will be will be'!!
