Hazel,
One of my old wishes, " I wish I was more laid back" ! Now I make my own wishes come true and if I am having a bit of high anxiety I go with it, let the feelings out, give myself breathing space and remember what matters most to me.
Many people spend their entire lives trying to prevent bad things from happening. But guess what? They happen anyway. And life goes on. That's not to say you shouldn't take any kinds of precautions in life, but if the majority of your thoughts are consumed in contingency planning, you're not enjoying life. You're preventing it. When you're feeling threatened by things that haven't happened yet, remember these words by Ralph Waldo Emerson:
Some of your hurts you have cured,
And the sharpest you still have survived,
But what torments of grief you endured
From the evil which never arrived.
Be well and blessings,
Kitt
