Dear Li Hua,

I have some problems. Due to the COVID-19, all of us now have to keep social distance and take online courses at home. I find it hard to constantly focus on studying. I feel tired easily. Worse still, I have become so anxious and short-tempered. I do want to change the situation, but I don’t know how. What should I do?

Yours, David
