I so understand how hard it is to stop the anxiety that builds every time.
What helped me was to make a plan for "next time". Planning well now will give you an alternative to the feeling of insanity while you wait.
Next time, perhaps have a plan to go for a walk, find a meeting and go, go to the library and find some terrific books that will take your mind someplace safer, or work out at home or at a gym to relieve the stress and tension....anything that will be good for you and will take your focus back to you.
Make a commitment to yourself to do this, and then when it's done take a good look at how you feel compared to how you feel when you just sit around worrying.
Your recovery, like mine, is about progress not perfection. Baby steps, just doing one thing differently than today are how we begin a better journey one step and one day at a time.
Think about this, make a plan and please let us know how it works out for you, okay?
Hugs
