Can you offer information on the recovery process as I have fear due to anxiety?

I want to have my nose done but I'm afraid of the recovery. I suffer from anxiety and panic attacks disorder and im afraid of not being able to breathe through nose after the surgery. For how many days you can't breathe through nose during recovery? In anxiety periods I couldn't breathe properly so it will remind me that memory and trigger anxiety or panic reactions. Please any information on the recovery process. And is piezo an easier method to recover concerning my problem? Thank you.
