Here is an excerpt (well paraphrasing) from the Panic Away program I have...its an amazing read. I'll be glad to send it to you via email if you'd like.

Observe:
When you observe the initial sensations that usually accompany a panic attack,
acknowledge to yourself that now is the time to apply your new learning. You’re not
setting the scene to have a tug of war with the anxiety as before.

Embrace:
Embrace the fear as it rises within you. Mentally send it a short message telling it
that you’re glad it’s come to visit and you’re sending it a warm welcome. Invite this
feeling into your body and mind, and treat it like an old friend.
Be firm. Just watch as the feeling of fear rises and draws nearer. If you’re a visual
type, you might want to give the anxiety a mental image, such as a troublesome
child or ridiculous cartoon character with big feet.

Demand More:
Demand more! Scream out, if you must, but let your anxiety know you’re making a
firm request that you want to experience the very worst it can throw at you! The
request for more is the most empowering statement you make when in the midst of
a full-blown panic attack. It sends a clear and strong statement that you are calling
fear’s bluff

Here are some mantras you may use to fully process the fear:

"I feel anxious and my heart is beating fast, but now show me how it
feels to be more anxious, come on heart beat faster! Is that as fast as
you can go?"

"Show me what it’s like if my throat and chest feel even tighter.
I can feel a real knot in my stomach, but I wonder what it would be
like if it were much tighter. Can’t you make it tighter? Is that the most
you can offer?"

"I notice all kinds of fearful thoughts circling around my mind. Make
them faster. Aren’t there any scarier ones?"

This request for more is a request that fear cannot deliver. You voluntarily move in
the same direction as the sensations, and you give no momentum to the fear to
create the internal tug of war struggle.

Trust:
This is where you need to trust you are safe. Trust yourself. Trust in your own
body’s ability to handle the situation and all the unusual bodily sensations you
might feel. Trust that you can process this fear and that the anxious thoughts you
experience are not valid.


Hope it helps.
