My 'toolbox' includes strategies both physical and theoretical.

I have an anxiety bag full of things like a worry stone, a tin of coffee, and gum. The idea is that you stimulate yourself with physical things than evoke your senses. This gives you somethingelse to concentrate on. Now, I am able to simply think of these things as needed - the scent of coffee is probably my favourite.

Cognitive Behaaviour Therapy (CBT) has been a great resource too. I developed some greaat strategies.
