Anxiety is a very crazy (in mind) thing. You must concour it to proceed.
I do agree.  I am lucky enough to have not suffered from it but my friends have.  They would feel nervous and have trouble sleeping. It is such an unpleasan state of inner turmoil. 
It is something that I suffered from, we must face our fears and deal with our pure emotion. Life is nothing but a simulation.
You are brave talking about it. My friend suffered from the restlessnesss and fatigue and concentration problems but it was only when she spoke out about it that she was able to get the help she needed.
Absolutely, knowing how to get to the center of the emotion is important. Begin by speaking with yourself and noting how you feel.
It is a very difficult thing to manage but you are right.  Dealing with the emotions, all conscious experience involved and understanding how you are feeling is the first step.
