Why doesn't anything interest you anymore? When did that start?
Since childhood, I have been isolated. I do not want to mix with people. I am not interested in being in a friendship or relationship with a girl friend.
But there were some things that interested me, such as video games, anime, and cartoons, some sports such as football, reading, studying science and delving deeper into it, and travel.
When I reached the age of 18, my existential crises began to control me. My childhood trauma began to have a stronger and more influential effect on my mind. At that time, all my interests disappeared except for a few things like anime Browsing the Internet and reading.
After that, I became nihilist and lost the meaning of life in the first place, and all my hopes became death as quickly as possible. Of course, my difficult financial circumstances contributed to all of this, and my depression became deeper and more severe as time passed. And here I am waiting until i end all this suffering soon.
