You are not stupid! Nursing school is not a cake walk. I had similar issues in Lpn school,4 kids and all. I found I was over studying. When I look back now, when studying,though details are important, also grasping the big picture is as well. As for nclex questions, you just have to pick the "most right" answer. To do this you have to look at the question and just pick the one that answers the question completely. Hang in there...it's worth it.
