Is there a difference between being shy and socially awkward?

I feel like shy = you’re too stuck in your head to take action ,

whereas socially awkward = you’re stuck in your head but you are taking action

(eg. when you are faking confidence ➡️ it is not congruent/authentic ➡️ thus come off as socially awkward)

basically “when your behaviour/action doesn’t align with your thoughts/beliefs” (?)
