For me the best route to take is a lot of postive self-talk. That is key for me while having anxiety or panic. If it's panic then that self-talk with abdominal breathing, for me talking is the best thing to do, it is over way quicker.

Knowing that it is the anxiety, knowing it is there. Telling myself that it is o.k to feel this way, it is uncomfortable, but it will pass.

Talk like that does wonders.
