Is it OK to panic now?

I’m off to Italy on Friday-can I have a moment for a panic attack? It seems like I have all the important aspects of the trip covered and yet there’s a lot I feel insecure about. Right now I’m terrified to the verge of nausea.

"Time is running, got to go
Fate is coming, that I know..."

I need someone to tell me it'll be OK, even if it's a lie-I'd buy anything right now.
