Talk to your friends or roommates. Whether they can help you out or not, at least it's better to say it than to hold it back.
3. When the epidemic situation is stable, invite friends out to eat delicious food, go shopping and ride a bike to see the scenery. When the mood is low, nothing goes well. It is better to take time out to play (not to brush videos) but get twice the result with half the effort.
When you feel comfortable, think about the solution to the problem. Maybe it will be a flash of inspiration. Studying and working are important, but as adults, we should learn to adjust ourselves and give ourselves time to relax, instead of working hard and racking our brains. I hope my answer can help you?
