Hello, I'd like to help you with your question.
The short answer to your question is nothing will happen to you. It helps to understand how anxiety
works so you know why nothing will happen if you panic
in a situation that you cannot get out of.
When you are anxious, your thoughts are causing your mind to think your in danger, such as when you feel trapped in a situation or place. Your body reacts by releasing adrenaline into your system. Adrenaline cause you to feel the body symptoms that are common with anxiety. It is much like after you have had a bad scare except with anxiety, there is no focus. The only thing you have to focus on is how you feel. However, after a period of time, your body releases enough adrenaline that it starts to deplete. In other words, your body cannot produce more adrenaline so it reduces and no longer causes the anxiety symptoms you are feeling (such as wanting to leave the situation you are in). If you can wait out your anxiety for a few minutes, you will find that you begin to relax and feel better after a short period of time.
It also would help you to consider short acting medications that you can take when you begin to feel anxious. Ativan or Valium are both medications you can take as needed instead of all the time. This can provide you with a way to calm yourself and therefore stay in the situation until the anxiety can pass.
Anxiety is also easy to treat with therapy. In therapy, you learn to pay attention to what you are thinking to make yourself anxious. The therapist then can help you change your thoughts and therefore how your body reacts to your thoughts. You also can learn about how to let yourself float through your anxiety thereby gaining more control over how you feel. When anxiety comes on, you allow it to flow over you without tensing or panicking in response. This makes the anxiety reduce or go away faster. To find a therapist, talk to your doctor about a referral. Or you can search on line at http://therapists.psychologytoday.com/rms/.
You can also help yourself at home. There are numerous resources to help you learn more about anxiety. The more you know, the more control you will have over your anxiety. Here are some to get you started:
