It's not your job to bring the panic attack to an end; that will happen no matter what you do.
Your job now is to see if you can make yourself a little more comfortable, while you wait for the attack to end.Here are a few techniques that I have researched that people have said are effective.
Regardless of what else you do, do belly breathing. It's also known as diaphragmatic breathing, but I think "belly breathing" is more descriptive. Many people think they know how to do deep breathing, but don't do it correctly, so they don't get good results. A good belly breathing technique is a very powerful tool in the work of overcoming panic attacks!
How to Talk to Yourself
Talk to yourself (silently!) about what is happening, and what you need to do. One question my patients find very helpful is this: is it Danger or Discomfort?. Some of the other responses my patients like include the following:
1. Fine, let's have an attack! It's a good chance to practice my coping techniques.
2. Answer your "what if...?" fears by saying "So what? I'll get afraid, then calm down again."
3. It's okay to be afraid.
Get Involved in the Present
People don't panic in the present. People panic when they imagine something bad happening to them in the future or in the past. This is why your panic attacks are almost always accompanied by some "what if...?" thought. If a dog just bit my leg, I don't say "what if a dogbite?". The reason you say "what if...?" is because what you fear is not actually happening!
Get back into the activity you were engaged in prior to the attack, and become involved with the people and objects around you. If you're in a store, resume shopping, reading labels, comparing prices, asking questions, etc. It will move you closer to your goal of overcoming panic attacks when you bring your focus and energy back to the present environment. By this I mean, work with what is around you.
Work with Your Body
Identify, and relax, the parts of your body that get most tense during a panic attack. This typically involves first tensing, and then relaxing, the muscles of your jaw, neck, shoulders, back and legs. Do not allow yourself to stand rigid, muscles tensed, and holding your breath. That just makes you feel worse! If you feel like you "can't move a muscle", start with just one finger!
That's "Actions (to make myself more comfortable)". How does that compare with what you usually do during a panic attack?
This step is here because you might start feeling better, then feel another wave of panic. Your first reaction might then be to think "Oh No, it didn't work!". The Repeat step is here to remind you that it's OK if that happens. Just take it from the top again. It's not unusual or dangerous. You may go through several cycles, and you just need to repeat the AWARE steps again, as often as you need.
