When everything is dark - I mean, when you really get to that point, a person is sitting in a certain room, there is no sound everywhere, it is darkness, the only light is the light displayed on the computer, and the computer cannot access the Internet, listen to songs, or read novels. When something like that happens, you will never feel panic, fear or loneliness like in the novel.
While I was writing this, the cold wind blew from the window. I wore a coat, but I still wanted to shiver. I am typing this in the environment described above. My heart is absolutely peaceful and calm, which makes me deeply understand: no matter what your environment is, what really changes you is your mentality; whether there is someone by your side or not, as long as you think you are not lonely, you never need someone to accompany you.
