I have no strength during the day, I can't sleep at night, and I may be homesick again. I think it's because I miss my loved ones or my work and life are too stressful. Insomnia is hard to avoid without stress. People are under pressure, so you should relieve the pressure first. If you are in a happy mood, you will have no strength during the day, and you can't sleep at night. You may be homesick again. It should be caused by missing relatives or too much pressure in work and life. If people don't have any pressure, it's hard to avoid insomnia, so you should relieve the pressure first and have a happy mood, and you can change.
