Not homesick yet

I'm extra tired today. We got to visit our client's office buildings in the morning and stay there for the rest of the day. We had both lunch and dinner with them, and by the end of the night I was exhausted. On the way back to the hotel, I was dozing off in the backseat. After I returned to my room I cleaned up and relaxed a little. Tomorrow I will need to check out, so I started sorting clothes and packing stuff. Some people are leaving on Friday, some on Saturday. I am staying for another week. I am not homesick yet, just tired.
