You may have finished your question to the doc but don't remember it

The recovery room nurses do urge the patient to wake up and stay awake so they can gauge how you're doing: if the anesthesia is wearing off, if you are nauseas (used to happen to me until I learned to tell them ahead of time that anesthesia does that to me; now they give me something to prevent that ahead of time), if you are in pain (they want to get you on pain meds soon and prevent it from getting really uncomfortable), and things like that. They need you to be awake to help them take good care of you.

Also they might tell you to move your feet to get you moving to prevent blood clots. All part of the initial recovery process and part of good attentive care, even though we might really really prefer to sleep

Feeling afraid is surely understandable when having to have surgery/anesthesia.
