Current concern

These days I had a fever, so I asked for a sick leave for a few days. I had to stay at home. Although I took medicine on time, it seemed did not work a lot to for me. I have missed many classes, which has made me a bit restless. After all, I still have some confusion about my advanced mathematics to handle and I really worry about it! The anxiety likely would not be beneficial to my recovery, but I could not stop myself. All right, I had better try to take it easy. I hope that I will return to normal quickly and catch up with others as soon as possible.
