Social Anxiety is,

Hearing people laugh near you,

Not talking because you're afraid that what you say will be judged,

Keeping quiet in a conversation with three people,

Not being able to go anywhere alone,

Staying inside all day,

Hating when the teacher asks you a question in class,

Eye contact,

Eating in front of people,

Counting money before you pay,

Not leaving voicemails,

Paying for things at a shop,

Asking for help,

Always preparing what to say,

Bumping into people you know,

Feeling embarrassed all the time.
