Do you often stay up until 5 or 6 or even all night?
Feeling like emotions and desires have disappeared and the whole person has become unusually calm?
But the moment you leave the house, you get inexplicably scared and bored and clogged up inside?
My friend, a warm hug first~
I've read your question carefully, and I can sense your current state from the description, but since I don't have more details, there may be some parts of my advice that you need to sift through on your own, and the following is for your reference:1, the work and rest is reversed, often five or six o'clock to sleep or even overnight.
Judging from your routine, there are probably two things: one is required for work, such as night shifts; but I think you are more likely to be in the second category, and I don't know what exactly you are doing when you stay up late? For example, swiping your phone, catching up on dramas, reading novels, swiping short videos or playing games, etc.

2. Feeling loss of emotions and desire to become very rational.
Emotions often arise because there is something unresolved, and once the problem is resolved, the emotions naturally dissipate. As you have noticed, the loss of emotions and desires makes people seem especially rational.
3. Once you go out, you will have fear and boredomHow long has it been since you've been out of the house? If you stay at home for a long time, it is indeed easy to feel this way, especially when there are still unprocessed things outside, people will instinctively choose to escape. But running away won't solve the problem. Only by facing it head on can we find a way out. There is always an answer to every question, just not yet, don't worry too much.
It is recommended that you take the time to go out more often, starting from the doorstep, such as sunbathing, and slowly adapt to the outside world. The same goes for your routine, which can be adjusted gradually, such as asking yourself to go to bed before 12 o'clock, and then slowly return to the normal time. Only when you are mentally well will you have the energy to do anything else.Cell phone messages can be turned off except for the necessary ones, including the entertainment apps you often play, or just delete them if you can't control them. Adjustment takes time, don't rush.
Have time to read more paper books, more exercise to enhance physical fitness, cultivate some hobbies, make friends with like-minded people, I believe you will get better and better.I hope these suggestions are helpful!
Looking forward to seeing a better you~ The world loves you with us~
