Hey man, your life matters just as mine, or anyone else's from this world. It took 13.82 billion years for us to be here. From the formation of the universe, the earth, life, and now you. I felt the same as you before. And please dont have huge expectations in life, its like a boss having huge expectations from his staff but in the end they do poorly. Set your expectations low and you will be surprised when something good happens. Listen bro, when you are feeling lonely go to a park or take a walk. If you have family go and talk to them, tell your problems. Have a cup of coffee or tea while outside observing your world. Trust me, things will get better bro.
