Yesterday, I stayed up late playing with friends and ate some delicious food, but this afternoon, while exercising, I felt sick, threw up twice, and came home feeling unwell. I had diarrhea three times, so I suspected it was enteritis, but I couldn't even take a taxi to the hospital. My stomach was bloated. So I asked my friends if they were sick, and no one said they were, so I told my family on KakaoTalk, and my mom got off work early and went to the hospital. I was even more worried because my college graduation is tomorrow, so I had to get to the hospital quickly. Thankfully, my mom and I went to the hospital early, and she diagnosed it as norovirus and prescribed some medicine. I took it, and in less than 30 minutes, the nausea subsided and my physical condition improved significantly. Visiting the hospital is the best when you're sick. I think I'll be able to go to the graduation ceremony tomorrow.
