What is the best way to stop a panic attack?

The best way to get through a panic attack is to practice deep breathing and giving yourself positive self talk. For example, if you are panicking over a test, keep telling yourself "I can do this! I'll make it through today!" And if you haven't seen a counselor for this, be sure to seek professional counseling and talk to your doctor about possible medications. They help a LOT! :)

Relax. Take deep breathes and calm your nerves Forget all the stresses and worries of the world you will do just fine don't worry:)

For me I get into the air, take a few deep breaths and then I do a quick meditation it helps me clear my mind and stay centered

There is several ways to stop panic attacks. One of the most common ones is diaphragmic breathing. What also helps, would be ASMR. Chewing gum will help you calm down, as it convinces your brain that you are eating, so you can't be in danger.

I have suffered with panic attacks. It make you feel scared and frightened. Remember lots of deep breaths. Count really slowly up to 10 in your head still taking deep breaths and you will find the panic has passed.

Grounding (focusing on your 5 senses, Sight, smell, touch, taste, hearing.) Counting to 10 and telling yourself that if you can make it through 10 seconds, you can do it again together with deep breaths and counter anxiety thinking eg.. I'm going to die this is going to end this is terrible as compared to, i'm not going to die, i might feel like i am but i know that i'll be okay once this feeling passes. If not, I will brainstorm ways and talk to people who care about me about this.

Put your hands up above your head. Acknowledge the panic attack. Seek the cause of it and try some grounding techniques.

Stop everything you are doing and sit on the ground. Breathe in slowly. Hold your breath for a few seconds. Breathe out slowly. And again : breathe in, hold, breathe out. And again. When you begin to feel better, ask for help around you. Try to find a calm and quiet spot where you can rest for a bit. Eat something, drink some water.

Breathe deep. Think of the things that make you safe. Let your mind wander to a different subject and explore a completely different element.

Panic attacks seem to be composed of two main factors for me: sensitivity to stimulus and time. So, it's critical for me to address both of these components when trying to stop a panic attack. Often the panic is induced by some external factor (like a deadline, a threatening person, etc.) that is being allowed to carry far too much influence in my mind. While it's easier said than done, identifying that external factor and putting some distance between us is the best way to stop the attack. Meanwhile, time becomes distorted for me during a panic attack. It seems to move faster or slower depending on the situation which seems to multiply the fear and dread of the attack, so keeping a watch with a second hand on it helps me. I focus on the steady ticking of the clock to bring myself back to normal speed.
