I am 15 years old and I just saw this article about this girl who died right after graduating from college and so I started thinking about death and how i could die any second. I recently accepted that there is no afterlife, before i had doubts, but now I am 100 % positive that there is no afterlife.This is what scares me so much though. I wish there was a god and an afterlife, even if i went to hell that would be better than this. I could die at any moment, maybe tomorrow, and that would be it. I would be nothing, there will be no me. I wont be able to think anymore, i will just be gone. It scares me so much that i could just die tomorrow and I wouldn't have even finished high school. I always just assume that i will go to college, become a nurse, fall in love, get married, have kids....but what if i do not get to do any of that? What if i die tomorrow or next week or next year? How do I get over this? What is the probability of me dying before i turn 40? I do not want to just stop existing.
The aspect of death is a common fear a lot of people have. I would highly suggest exploring some Existential therapy, which helps people to accept the givens in life (such as death): I would also recommend a book called "Staring at the Sun" by Irvin Yalom (the founder of Existentialism) that deals with overcoming the fear of death:
The teenage years is when you realize dwarh is real.
