Is it normal i am afraid of death only because i'm not sure about afterlife

I know EXACTLY how you feel, and here are a few advices: You can't trust religion 100%, but only because God wanted it to be that way. Life is sort of a test. If God has said "hey humans, here I am!" Then everyone would know that he existed, and take him for granted. But don't worry, God doesn't get angry at you for being afraid of death and trusting science!
If you did not trust the unknown, you would not be human.

And to all the people shouting "God is impossible because of science!":
God created science. He created the Universe so that it would have laws of nature & physics. I know that the idea of a God sounds improbably in our Universe, but that's only because...well...He isn't in out Universe. The laws of nature do not apply to him. nature does not apply to him. Humans have become so used to living in a world where everything makes sense, that believing in something that our Universe do not support, feels Impossible.

Oh, and here are some advices:

When you feel really bad and depressed, go into a place you can be alone, and pray to God & Jesus Christ. They will listen! Just ask them to care of you, just ask them to give you the strength to get through the day without falling into the pit of despair!
Trust me, I do this when I feel down. It really helps.
Trust me, it really does help.

I gave up trying to analyze death and the possibility of an afterlife. Basically, we are living creatures and we simply cannot comprehend the act of not existing, since existing is everything that defines us. Trying to understand death is similar to a man who is born blind and tries to understand color, though at a much larger scale. Thinking about it is ultimately pointless, it's not something your mind can grasp. Let it go.

It's very very normal to be confused about afterlife

I'm agnostic. Why? Because the truth is nobody knows. I could research it my whole life but I wouldn't know for certain. One thing that we know for sure is that everybody dies. What happens to them past that point is what's controversial. It's really not as bad as we all think when you think about it. Were you afraid before you were born? You don't know do you? That's because you were in a state of non-existence. That's all death is. (Unless there's an afterlife) There's really nothing to be afraid of. Just enjoy life and live it to your liking. That's all there is to it.

Being Atheist isn't just about "believing" in science and rejecting religious beliefs; this isn't the best way of describing it and it's a little misleading. Technically, being Atheist means you don't believe in a god(s).

For me, I'm Atheist, it doesn't feel like I have to believe or not believe in anything, it's just not an issue. It's sort of like believing in Santa Clause as an adult; you don't sit around thinking about not believing in him or talking about how you don't believe in him with your friends - you just know that it's make-believe and you don't think about it unless you are trying to get your kids to believe in him.

I spent a couple of years curious about what all the hype was about as far as religions go, and explored them to great length, but I always felt like I was trying to fool myself. It didn't feel much different than trying to believe in faeries and unicorns when I was a little girl. It seemed like a nice idea and I wanted so badly for it to be true, but in the end, it just seemed too ridiculous to take seriously. I felt so much better when I just let it go and got real with myself about it. Now I feel a little foolish that I ever wanted to.

Maybe you were never really Atheist, maybe you were only Agnostic.

The best thing you can do, is do what YOU FEEL is right in your heart/soul. If you are not ready to accept that everyone has to face death eventually and that could mean there is no "heaven", then maybe religion may be a comfort to you. And just remember: no one really knows, not even the religious folk, what happens to your soul/spirit/energy after you die.

I hope you can figure this out. :-)

I seriously feel exactly the same way! I am Christian but very very afraid of there being nothing after death... It is totally normal!

I'm in the EXACT SAME situation. Makes me feel better that there is someone else out there.

i just dont think about but just incase, im not going to go around killing ppl

well, we all owe a life one way or the other. why spend time worrying about what the hereafter holds? if we live a good life, we have nothing to fear.

I feel the same way. No one can know for sure, right?

Oh, I have one more thing to add...

I grew up Atheist, but I didn't know that I was Atheist until I started exploring religion. I wasn't familiar with the term and what it meant exactly. In my family we didn't go to a church/temple like some of the kids I went to school with and we didn't talk about god(s) at home.

If you think about it, the heaven and hell theory seems very unrealistic.
Reincarnation seems more probable.
Even so, you can never know for sure.

I think every human being goes through this at some point. I had what I would call a complete existential crisis about a year ago; I wasn't religious like you, I just collapsed into this miserable atheist heap and all I could think about was how life was meaningless because everybody dies, etc., etc. (I don't recommend doing this, by the way, I almost tried to kill myself. I think I was saved by a mixture of terror, music and Buddhism, as well as medication, but anyway...) Jack's advice is actually good; instead of thinking about dying, or whether or not there's a Heaven, remember to live your life and that those are things you can't possibly control. Learning to accept that is really important.

o hade the same thing i could eat sleep and i woulded talk to my friends but then i started to think if im so wered about dieing i was not lifeing so every time about dieing i think about bout that. so yea lie life to the fullist i hope this helps u and im i guy
