This is how I emote during the lead up to a new trip:

Pre-ticket purchase – “That would be so cool!”

Ticket purchase – “WOOO!!! I’M GOING!!!”
This ebbs and flows slightly depending on how much I’m thinking and being reminded of the trip, but generally stays pretty high. For a few months, life goes on, but the anticipation stays high.

Two to one weeks out – “Oh man! I’m so excited, it’s coming up!”

One week to two days out – “Shoot! So much to do! Stressssssed!”

The day before – Stress + “Wait, I’m really going to miss you all! And I wanted to do that thing that’s happening while I’m gone. Sad.”

The night before – Poor sleep.

The day of – Freak out I’m forgetting something.

On the plane – Siiiiggghhhhhh, I can finally relax.

Land – “YEEEEAHHHHH!!!!!”
