How do I dominate and destroy my anxiety?

Most days I’m confident over my anxiety and I know I’ve made and continue to make good stride against it. But every once in a while, when the stars are aligned, and the right amount of stress, worry and doubt creep into my head mixed with a “waiting for a physical stress sign like a chest pinch or something” I will still freak out and it’s hard to overcome in the first 2 minutes. I don’t go full blown anxiety attack but my heart does race and I have to calm myself down. Luckily the breathing is usually really well. But it’s hard to forget the initial sting pinch in the chest feeling also possible heart palpitation.
