Feeling sick in New York

This morning, I got uo early in order to join the Harlem walking tour at 8:30 AM. I wasn't feeling too well when I got up, but I tried to ignore that and make the most of the day. The tour wasn't too interesting, the only thing that caught my attention was a huge cathedral. It was beautiful even though the cathedral wasn't even completely finished yet - our guide mentioned that this might still take a long time as there was currently no money for that.
We ended our tour in front of a church, where a gospel service was about to take place. I had really been looking forward to this service. Nevertheless, I had to leave early: While I was sitting there, I had the feeling that something or someone nearby was stinking like piss, which was kind of disgusting. Maybe because of that or maybe because I hadn't been feeling well since I got up, I suddenly felt extremely sick, like I could throw up any minute. Even though it was in the middle of the service, I knew I had to get out of that church.

I felt a little better when I was outside, but I still decided to go back to the hostel. When I arrived there, I had a bad headache, so I just lay down and tried to sleep a little. When I woke up later, my headache was better already. Unfortunately, my throat had started to hurt now. I didn't want to just lie in bed all day long, so I decided to go out and look for a grocery store. I needed to buy water and a few other things. Luckily, there was a store about two blocks from the hostel. After I brought my groceries home, my headache got worse again. Consequently, I lay back down and slept some more.
Around 6 PM, I was feeling a little better and since I hadn't eating yet. I went downstairs and had spaghetti for lunch/dinner. After that, I went down to the movie room, where a few other people were already watching the news about the election. As I had nothing bette rto do, I joined them for a while.
I went back upstairs around 8 PM and spent the rest of the evening just relaxing and reading.
