If God responded to you, then that's called psychosis, I had it. God is just Santa for grown ups, and whether he exists or not is up to you. I recommend that you don't try to speak to him in your head though, because that is without doubt a manifestation of psychotic delusion. Maybe reciting a prayer isn't so bad, but to think that he's actually listening, that's beyond the pale. I have no doubt that our ancestors knew that what they were doing when they were reciting prayers was not meant to be a conversation, but more of a mantra, something to guide your intent toward goodness. So yes, forget all that stuff, and don't be too dramatic about it, just decide what path you want to take in life, live it, then die. There's nothing special about anyone.
