You sound like me...and how I was a while ago. I saw the Hennipin brain trauma centre at 6 months post, or so. Some good people, and most of them get it. See if you cane get referred to Dr Marian Rubenfeld, neuro-opthamologist in Minneapolis and area. heaven sent.
hang in there. My son (11) said to me the other day that he thinks I am getting much better (16 months on) and when I asked him why, he said it was because he rarely hears me crying at night. Yikes! I actually tried not to cry too much because it hurts a lot and leaves me with a massive three day headache. How ironic that when we need to cry and should cry, we can't!!

Hang in there for your kids. It will get better,
