Anxiety is the vague, uneasy feeling you get when you're dreading something. Anxiety can also be a permanent state of nervousness that some people with mental illnesses experience, a milder version of panic.
When a scary or unpleasant event is looming, like getting a family portrait taken the year you have braces, you might feel some anxiety. You might also feel anxiety about passing chemistry, especially if you’ve skipped a lot of classes. Someone who suffers from a mild or severe mental illness might feel anxiety all the time. Deep breathing, playing relaxing music, and medication have all been known to help reduce anxiety.
