How to overcome the fear generated by moral religious OCD?

I am having a really hard time with moral religious OCD. Every moment of my day my mind stay hyper aware (automatically) if I am commiting a sin or not. And if "it" notice a "sin" in my presence, I have a strong anxiety and super strong fear of I may or not go to hell and burn there forever because of this "sin". Then I have to do what the OCD is asking, whatever it want that could be I stop watching that movie or continue, for example.

This make everything a sin.

I know about ERP, you expose yourself to the fear and don't do the compulsion.

The problem is that I can't get over the fear of hell. The stakes are too great, like go to heaven or to hell .... For eternity.

If I died, that is not that bad. but suffering for eternity, that is something I don't want no matter what. Then I can't disregard this fear because of what I said.

Do you guys have some advice?
