Most people feel nervous in social situations, like having a job interview, going to a high school reunion or giving a speech. Most of us worry about what we're going to say, do or even wear during these events. These events often become easier with some experience. However, in people with social phobia (also called social anxiety disorder), these events and other social situations can be frightening and disabling.

Social phobia usually begins in the early teens, although some people have had it for as long as they remember. Others feel it coming on later in life, as social demands increase. It often runs in families. Sometimes it leads to other problems, such as depression or substance abuse.
