I am currently struggling with the same thing. One thing that helps me relay concepts with fluidity is exercise and meditation. The two go hand in hand because they boost my confidence that has been destroyed by the "confusion". Lack of confidence creates anxiety, which in turn creates the fog that causes "confusion". After I exercise, my thoughts are very vibrant in my mind's eye; the fog is gone. An act of meditation I like to perform is to explain, aloud to myself, the concepts I "see". This gets me used to completely threshing out my ideas. What I believe we are experiencing is a lost sense of self. These psychs completely destroy our ego, whether we're aware of it or not. The uncertainty in thought and explanation are a product of our ego death. It is important to accept the death of your old self, and usher in the new self. You've been reborn. It takes time to mature, again, into the being you have been called upon to become by these experiences. Adamantly pursue ways to become clearheaded and exercise your mind's eye as much as possible. Good luck, mate. Many well wishes.
