Are you extremely stressed out right now? Sometimes thoughts like that go through my head during times of extreme stress.

I have kind of experienced something similar, but it was more along the lines of existential rather than religious. Kind of like "I was made for nothing," "what am I doing taking up space on this planet?" It wasn't true nor accurate. I think this was just a result of the anxiety/depression that you've been experiencing.

Hope that you are feeling better soon!
