Do you experience racing thoughts that disturbs your ability to sleep? Do you have trouble regulating your emotions? Is it hard for you to sit still for extented periods of time or does your thoughts wander when you're sitting still? Do you forget to listen and pay attention to other people talking, to what the words say when you're reading, to the scenes in the movie you are watching?

These are just some of the many, many signs that could indicate that you may need to get tested.
