I was taught a lot of things were bad and I was going to hell if I did them so I understand what you mean.

I had philosophical issues with everything, I decided that I didn't believe everything I was taught. But, I would occasionally question something as small as buying a lottery ticket. I would question what I wore, thinking or feeling pretty because I was vain.

I think it's easier to deal with or even stop once you recognize that you're questioning it and that you always have been. I just realized that I question everything and why. I have become more genuinely confident just from that. I'm not cured of the questioning but it's a lot better. Good luck and listen to yourself, you know how you really feel.
