How do you study D&C?

I feel very overwhelmed by Doctrine and Covenants.  I don't feel like I can trust it and have a hard time reading it.  As I've gone through this process the past two years of learning the truth about Joseph Smith and Brigham Young I am having to relearn to trust myself and my relationship with the spirit.  Trust was broken there in a way as I feel I allowed myself to believe very false things in the past and claiming it to be the spirit. I am opening myself up to spiritual direction again but it is scary.  I know God will help me along this process but at this point in my journey I need any and all advice on Doctrine and Covenants. I can't trust to know that Joseph Smith actually taught the things in D&C. Every word in questioning. I need healthy ways to combine logic/reasoning/spiritual direction.  How have all of you navigated this? I'm open and humble, you can't hurt my feelings so if you see errors in my thoughts please say so.
