Just figure out what you believe, and live it. If you find that something is difficult to come to a conclusion on, perhaps something you have always assumed *had* to be answered, adjust your own attitude till you are comfortable with having a good question rather than a bad answer.
I find myself still playing “old records” in my mind and now questioning everything
The "old records" part? No big deal, as long you understand the source, and have decided to "question everything". That "questioning everything" thing is good. Keep it up.
