The way people feel is often very apparent to sufferers of anxiety.
Being anxious makes a person inwardly focussed, which in turn causes problems with self awareness.
Unable to focus attention on the world around us, forces our mind to take note of our actions.
Part of the recovery process for dealing with anxiety focuses on outward thinking, less focus on ones own self lowers anxiety and especially in social situations.
Anxiety is a feeling.
It cannot be seen or felt by anybody except yourself.
Sufferers of anxiety often feel like their apprehension is very apparent to the world around us, when often it is not.
Think about the last anxious moment you encountered, did anybody comment or acknowledge the fact you seemed anxious? Although these feelings are often never picked up by other people there are certain physical symptoms that do sometimes become apparent.
For sufferers of anxiety these feelings are greatly amplified, which only makes the situation worse.
Anxiety feeds on itself.
You may find that things have became a continuous loop of negative thoughts, which affect our actions and day to day lives.
Common Physical Symptoms of Anxiety Include:

• Sweating: A real problem for me has been sweating.
  Underarm perspiration is a natural bodily function.
  It often becomes a problem the more anxious a person feels.
  They are then painfully aware of the problem, which again makes the problem worse.
  
• Blushing: Again, a natural bodily function.
  People blush all the time, it is natural for a person to blush in certain social situations.
  The problem is that an anxious person will be overly aware and focussed on the fact they blush.
  It will be so apparent to the person, it seems as though everyone in the room is aware too.
  
• Shaking: Trembling hands are very common in anxious people.
  Causing all sorts of worries especially in social situations.
  Shaking hands or simply people noticing the persons problem becomes a root of great fears and anxiety.
