Tell me about those people who want to sleep at night but can't.

Empty. The emptiness inside is covered by your thoughts. You start to think that sleeping is a waste of time, but you don't know what to do without sleeping. Why are you afraid of missing something? If this feeling is recent, then I think you need to adjust your life pattern. Find out the direction for yourself tomorrow. Your feeling is that you have been relatively empty recently, or you have discovered the inner blockage caused by the dark side of society. Or what happens between friends, causing spiritual alienation. At this time, it is often difficult to believe things around you and lose interest in life. I don't know what advice to give you, because what is often needed most at this time is self-regulation, although it is not so easy to say and do. Because you may think I'm talking about common sense that everyone knows. You need to relax yourself and give yourself a space to release. Try to do what you are interested in and want to do. If not, please try to find your own interests. Because people often become confused after losing their goals, don't know what they are doing, and then they will recall the past. And you need to make friends, make new friends selectively, and let yourself feel that life is full of firepower again. Travel can be a good way to relax yourself and let yourself be in a strange natural environment, feel and breathe. Memories are not a bad thing. When the present situation is not satisfactory, we will recall the happy days before. So, what you can do is to create happiness. Of course, it is also possible that your emotions last for a long time, months or even years. If so, you should see a professional psychologist. This is nothing to be embarrassed about. It will help you get out of the present situation as soon as possible and improve your mentality.
