Being acutely aware of your body and the most subtle changes, such as an increase in heart rate, can be a catalyst for anxiety...causing your body to shoot out adrenaline which can lead to some or all of these symptoms:
Chest pain , tightness or discomfort
Fear of dying
Fear of losing control
Tremors Dizziness or feeling like you might pass out
Numbness or tingling in the hands, feet, or face Palpitations
Fast heart rate
Shortness of breath
Feeling like you are choking
Feeling detached or disconnected from reality Feelings of impending doom
For example.. you bend over to pick something up…. Your heart rate goes up.. you become aware of it and become anxious …now starts the barrage of symptoms and a full blown panic attack. Your body is producing adrenaline and the symptoms keep on coming…
The single most important thing to remember is that THIS CAN NOT HARM YOU. It’s just the adrenaline ….. and it WILL pass.
The scary thing about Anxiety is that it can seem to come out of nowhere.. without a concrete cause that you can pinpoint. Anxiety can cause alterations in breathing patterns and it may be that you are holding your breath or breathing too rapidly which can cause fatigue and the symptoms you are experiencing. There is something you can do right now to stop it..... initiate proper breathing. You can help alleviate the feeling of throat tightness, panic and and shortness of breath by changing your breathing pattern to abdominal breathing. To abdominal breathe ( which is a much more effective breathing technique) place one hand on your abdomen and one hand on your chest... watch to see which rises. It should be the abdomen, NOT the chest.Practice breathing using your abdominal muscles... (to breathe with chest muscles causes fatigue and more shortness of breath) by taking in a deep breath through your nose.. making sure only the hand on your abdomen moves, slowly.. and exhale slowly through the mouth.. your abdomen should flatten with exhalation. Do this three breaths at a time. Breathing correctly will immediately eliminate anxiety...., every time. If it comes back do it again. Here is an excellent link to read more about anxiety:
