Ive found that in my studies I always wind up in that same position after about 3 months or so. Also, think of it like a video game. Ever play a game and you just cant get past one part? But then if you put the game down and come back after a couple of days you beat that level on your first attempt? Take a break. Sometimes we need to get out and see some trees in order to get the inspiration we need to make any progress.
It's easy to want to be 'the one' to figure it all out but we are racing against them, not each other. When I figure it out while you are taking a break I'll include you in a footnote somewhere towards the back of my dissertation :^)
