Ok, so here's my interpretation.

The song name is Prayer thus must relate with praying and with god.

Looking at the verses, it only states a bunch of misfortunes: "Another dream that will never come true", "Another life that I've taken from you". Those are clearly from god.

Now, the chorus is not from God. It's the response from whoever God was speaking to. Let's call him man. Here are my thoughts: "Living is not hard enough" and "take everything away" parts are sarcasm. You keep throwing misfortunes at me while my life is already hard enough. Sarcasm: "My life is not hard enough, keep going..."

About "Let me enlighten you, this is the way I pray", I think it's from the Man who responds to god in objection. Like "Let me tell you what I think about you now".

Lastly, the part "Return to me" and "leave me no one", "Cast aside". "Return to me" is the Man who was praying to god, but kept getting denied "Leave me no one", "Cast aside". This led the Man to turn away from god "You've made me turn away". It's your fault.

As a final note, since the singer is only one person, the verse are not really God speaking but instead how the Man views god. Like "you stole someone from me", "Another nightmare is about to come true", etc. but speak to it as if God does that voluntarily which shows how much he lost faith already. Like the only thing god bring is misfortune.
