Outward Signs  - One of the difficulties of being shy is that it is very often impossible to hide your shyness from other people.  Signs of shyness include frequent trouble talking, stammering, stuttering, blushing, shaking, sweating hands.When these things start to happen, the shy person often becomes more upset and less able to deal with the current conversation or situation.   Please keep in mind that these things happen to everyone sometimes.  We all get nervous in new situations and  then the more the nervousness  is thought about, the more nervous we may become. 

Inward Signs - Many shy people have both inward and outward signs of shyness.  However some people can act confident on the outside, but feel miserable on the inside.  While these people act very self-assured on the outside, inside they have a racing heart and almost constant thoughts on how the conversation is going, how they look, if the other people in the room like them, and how quickly they can leave the situation and return home.
