What happens when we die?

I would first off like to say this thread isn't about religion or preference to a certain faith. Whether you believe in God or not, everyone wants to know deep down what happens.

As most people should know when our body finally realizes we are dying it releases a chemical named DMT into your brain. You can look this up, it's an actual drug you can get your hands on but the people who have taken are changed forever. You basically see death or what technically happens after/during death.

I personally believe in God, I'm a confirmed Roman Catholic but I haven't been to church since I graduated High School. I don't believe in religion, church does nothing for me. I feel closest to my creater when I'm at peace, or admiring nature. For anyone who doesn't believe in God or a creator that's your opinion and one that should be respected. At the same time you feel peace in certain places and it almost feels like nirvana in a way, so you can relate to what I'm saying.

I don't know, I really don't know if I'm scared to die or not. I don't know if I should be scared or not. I've always thought that if I'm a good person and my intentions are truly good throughout life then what else can my creator or higher being ask of me? If that's not enough to get into heaven then I guess I'm going to hell.

I've always been really scared that when we die it's just nothingness, you feel nothing, you see nothing, you are nothing. I've had points when I was younger were I would seriously get anxiety over that thought, but now what if nothingness is the true form of peace? Nothing to love you nor hurt you, you're just energy and part of the universe forever. As you know energy can't be destroyed nor created, so all the energy in existence has always and will always exist.

If you think I'm a pussy or beta for saying this then you're a closed minded fool not to invest time into the greatest question humanity has ever faced.
