All is well. CampusFrance sent my completed registration, I printed the email at a FedEx office on the basement floor of a building on Michigan Avenue. Then, I arrived at the Consulate early, so I was able to submit all the documents for my visa by 10:30AM. Got a cab back to the airport and an early flight home.
Tomorrow is my dad's birthday, so I'm not going back to school until Saturday morning. It should be a fun time. I'm finally at ease with the world.
