To have clarity is to feel energised, resolved, focused, settled, decided. Anchored.
Confusion or hesitancy is the opposite. Unpleasant emotions that can be defined as questioning, indecisiveness, doubt, hesitancy, fuzziness can leave you with a sense of paralysis. Confusion or doubt makes you feel like you can't think clearly and make a decision on how you feel about something.
Confusion comes from reaching a point, where you can no longer stand by a belief you have held for a long time. Confusion leaves you with a sense that there is something you should know or explore, but not wanting to dig deeper because what you uncover could feel unpleasant or overwhelming.
