I am not an atheist, but rather an antitheist. As long as I'm still in my depressed state, I am repulsed by any and all forms of faith.
Currently, I have an extremely cynical world view:
There is no benevolent entity watching over us, nor is there a greater purpose to existence. There are no happy endings in real life, and everybody will suffer because the world is imperfect and corrupt.
Simply being happy is a sin by itself, because it is selfish to be happy while billions of people are suffering worldwide.
Altruism, sympathy, kindness, trust, and faith are naive, and they only exist in idealized fairy tales. You cannot afford to trust anyone, else people will take advantage of you. In the real world you can only rely on yourself, otherwise the people you rely on will stab you in the back.
If you're hurt and dying, nobody will help you. They'll either stand by and watch, or come and steal your valuable possessions while your life bleeds away.
Basically, I believe the world to be the polar opposite of the idealized God-made world you religious people believe in. If I have faith in something, I'm subconsciously convinced that only two things can happen to me: 1) the thing that I have faith in will turn out to be the absolute worst case scenario possible, and 2) people will take advantage of me because faith is naive. There is no heaven, there is only hell.
Am I having typical teenager angst, or am I going insane like I thought I was?
