Welcome to HealingWell and the A & P forum. You have described the sx of Anxiety but these same sx may be caused by other problems.
I agree that you should talk with your physician to make sure that you have know medical problem going on just to be on the safe side.
If it turns out to be anxiety, we have lots of great advice to help you through so please do stick with us.
To help you stay focused and keep your anxiety down try the Three-Part Breath
Find a place where it's quiet.
Sit in a straight back chair with both feet on the floor or lie on the floor with a straight spine.
Begin inhaling by expanding the abdomen (let it inflate like a balloon), ( guess your's already is.....
) Then move the breath into your rib cage and, finally, all the way into your upper chest.
Exhale by reversing this action; begin at your collarbones and exhale down through your rib cage and into your abdomen. Contract your abdominal muscles as you finish exhaling.
You might find it helpful to lightly place your right hand on your abdomen and your left hand on your rib cage to help direct the breath on its journey.
Begin by practicing for one minute and then gradually lengthen the practice to five minutes.
This technique helps to eliminate shallow chest breathing and encourages full exhalation and inhalation.
Once again, there's no need to push yourself or judge yourself for being anxious. The idea is simply to be
quiet for a short time and notice your breath. Take care and know you have found a wonderful and caring Family here in the A & P Forum.
