Also, please, help me!! I have a test in an hour and my anxiety is really high! I can't calm down!
You can help yourself by accepting that what you are going through is normal IN THE CIRCUMSTANCES. So called 'normal' people suffer anxiety when going for tests or physicals. In anxiety the feeling is there but greatly exaggerated. Everything in anxiety is 'normal' but it's the exaggeration that gets to us. You may not be able to calm down, but you can accept it all as how you are at the moment but won't always be. We often get phases in anxiety where everything seems to be abnormal and where fear seems to take over. At the moment your brain is sensing danger from the thoughts you are having. It is behaving normally by putting you in the 'fight/flight mode. This is something we have inherited from our ancient ancestors that enabled them to run away when danger threatened, and as such is normal. The failure to recognise that normality is what sends us into a spiral of anxiety.
You have raised a profound philosophical question. 'Who am I?' We are not who we think we are! When we are born the recorder is switched on and we take in everything around us. As we get older and become conscious beings we are inundated with ideas and concepts from other people, some good some bad. The ego begins to develop and takes over so that the purity of thought leaves us and is replaced by false ideas and premise from those around us. In basic terms we are 'brainwashed' into believing we are something we are not. It is as if we are in an attic with a blazing light, our true minds, but it's covered in layers of blankets. Our job in life is to remove those blankets (false ideas and concepts) so that the light can shine forth and so help others along the way. How can this come about? By questioning everything and deciding on its veracity. Is it true? Is it a truth I can go along with? How does this belief affect me psychologically? What effect is this belief having on my life? Over the entrance to the Oracle at Delphi are the words 'Man, know thyself'. A profound three words that are so important. Do we know ourselves? Christ said that we must become as a little child to enter the Kingdom of Heaven. No concepts or preconceived ideas. No dogmatism or arrogance.
