That is why when I started researching I considered that if what I believe is true, nothing can shake that, research would just convince me even more.

You are on the right path.
At a certain point, you're going to have to be okay with not knowing all of the answers to life's big questions. The organization tells us that all the existential questions we come up with have answers in their teachings. Unfortunately, this means that if you find out there are flaws in their teachings, you can have some really upsetting and panicky thoughts.
I remember a switch flipping where I was okay with having some questions unanswered.
When you get to that point, it's easier to examine evidence objectively.
