Unfortunately I experience the same somewhat hot and not periods with my God. I'm so thankful to know that He doesn't do the same. He doesn't come and go, I do. So it's helpful at the worst of times to know what I believe about God and His love for me is still true, weather I'm all there or not.
Sounds like you worked it out and got a good thing going. I do relate to the intense excitement about it all when I'm feeling more hypo than not. Then again, at those times I feel more intense and excited about everything, so it holds relation.
It is of utmost importance for me to know that God didn't 'break' me but will 'fix' me. That healing is His plan and sickness is not His doing.
Good luck x
Hope is what it gives me and at helpless times, there is still a flicker of that hope.
