We are just talking monkeys on a big rock in a random part of a beautiful, immense universe, believing in a random deity won't help you go better anon, it'll lead you to disapointment.
But that doesn't mean you're worthless, you're here with us, for this amazing trip that is life.
Find your own goal(s) : helping people, buying your dream car, becoming famous, seeing your favorite artist in concert, finding love...
It'll help you through hard times.
I fixed myself goals thanks to my hobbies, also I like making people laugh, I like to learn : I want to do this as long as possible.
Suicide is not even an option, find a way to enjoy the short amount of time you have as a living pile of atoms.
Suicide is the end of this chance, you can still hope for an afterlife if you want, you won't even be disapointed because after your death there won't be a "You" anymore. Just a corpse, and some people crying.
Hang on OP, no matter how hard is your life right now, there is still shit to do.
