Thanks for your response!
I've read your previous thread, I am sorry, that you had to go trough such things.
Guilt is, indeed, something that can be ingrained in ourselves as a result of our life experiences.
Do you live with your parents at the moment? Is so, is there a chance that you can move somewhere else?
Earlier you also said, that you still have feeling of being watched by higher entity. Is this entity resembles with Christ or is it some other deity? How do you think, why, considering your changes of view on religion, it is still important for you at the moment?
Anyway, the more you go away from this hard experience with religion, the more you will feel less influence of it in your life. You can go out to atheism gradually, for example, starting from Buddhism, there is no deity at all.
Or you can just learn more about evolution, psychology of your thoughts, it will make some things more clear. How do you look on that?
The main thing is do not blame yourself for any previous, current or future events. There is no use in guilt at all, because at every moment, why do you act the way you act?
When you listened to your parents and confessed in church, could you really not obey them at the moment? Considering your mental state, age, culture and many more factors, you did the only way you could.
And about that rope in your backpack...you know, I really like, what Emil Cioran said on this: "I live only because it is in my power to die when I choose to: without the idea of suicide, I'd have killed myself right away".
I think, maybe, it can be useful to you to learn his books a little bit, because he was born in Romania, very religious, Orthodox Christian country and them emigrated to France. He became atheist too, but he just couldn't let go of that idea of god, so he directly and indirectly wrote much about this topic.
