Well here is anxiety at work for you. I am up at 4 AM on the site which is for me my own special therapy. I loved to be able to help others so here I am.
Yes, please do get the thyroid checked when you can. It is another possible cause for anxiety. Some anxiety can be good for us but to much is not. If you find your self being over whelmed here is another of my favorite suggestions and it does work.
It does not matter if you feel frightened, disorientated, dreamlike, or unsteady. These feelings are an exaggeration of the normal bodily reactions to stress.
Just because you have these sensations doesn't mean you are crazy. These feelings are just unpleasant and frightening, not dangerous. Nothing worse will happen to you.
Let your feelings come. . Don't run away from panic. When you feel panic build up, take a deep breath and as you breathe out, let go. Keep trying. Stay there almost as if you were floating in space. Don't fight the feeling of panic. Accept it; you can deal with it.
Try to make yourself as comfortable as possible without escaping. If you're on a street, lean against a post or a store wall. If you're at the cosmetics department of a store, find a quieter counter or corner. If you're in a boutique, tell the salesperson you don't feel well and want to sit for a while. Do not jump into a car and go home in fear.
Don't indulge in stinkin thinking, "Why can't I be normal ? Why does this have to happen to me?" Just accept what is happening to you. If you do this, what you fear most will not happen.
Think about what is really happening to your body at this moment. Do not think "Something terrible is going to happen. I must get out." Repeat to yourself "I am ok, I will not die or lose control."
Try to distract yourself from what is going on inside you. Look at your surroundings. See the other people around you. .They are with you, not against you.
When the panic subsides, let your body go loose, take a deep breath, and go on with your day. Remember, each time you cope with panic and anxiety, you reduce your fear.
