I think it’s also important to point out that not everything is clear-cut in Judaism. There is room for different opinions. Of course sometimes, there is not. But other times there is. So it can be very confusing.
That’s why it’s good to find Rabbanim whom you can basically trust. Although outside of the Gedolei Hador, you shouldn’t blindly trust and accept every single thing that someone says. Unless it’s a clear-cut halachic matter.
But it will take time until you figure out who you can basically trust.
I still recommend that you check out Rav Leff’s website and listen to his shiurim if you haven’t already.
