Two days before the holiday, I found myself particularly fond of quiet, so quiet that I didn't want to hear the sound, then I stayed at home alone and then lay down and hated going out.

This is depression, which can be cured. Depression is a mental illness. Taking medicine can only inhibit the disease, but can't take root and sprout. You can go out more, invite friends to dinner, sing songs and think about happy things. The most important thing is not to take all your worries to heart, but to restrain your self-centered mentality. Don't stay alone for too long, you will fall into a paranoid state. The most important thing is to rely on self-regulation, or to see a psychiatrist.
