My experience is, this is common among former LDS. Burned once, big time, you mistrust not only religious claims but your own ability to discern.
I worked through each point that I was viewing with skepticism. For myself, I reached a point where I had to take a leap of faith, or turn back. It was a point where I was the camel, that God was trying to pull through the eye of a needle.
I viewed the turning back with the same skepticism. Obviously, the leap of faith is a decision I am at peace with. I can’t say I trust my ability to discern any more than I did before. I trust where God has led me. It is, in a tightly packed nutshell, what Christ calls us to do. Die to yourself, and follow Him. I know how difficult that is to do. It is a process, that continues for a lifetime.
Look to Mary, and her ‘yes’.
Perfectly ok to take the time to dig in. Conversion to Christ is a process, with no schedule and no timeline.
God bless you on your journey.
