May flowers or the battle for a correct diagnosis

This month is a grand month. I just celebrated my 20th anniversary, had a wonderful Mother's Day and will celebrate my birthday next week with wonderful women. I am grateful to be so blessed.
On the other hand, Tyler is still struggling through school. He did get some services but his teacher's feel it's not enough. He still struggles through mainstream class time. I'm working toward getting him diagnosed as OHI. He doesn't fit into traditional diagnoses. He is a part of a small, unique group of children struggling with non verbal learning disability. He will benefit most from resource classes which are smaller and provide more one on one help. Getting him this diagnosis is like pulling teeth. I have to get a doctor to provide a letter saying he suffered a brain injury. His neurologist and pediatrician he had at birth haven't seen him in years. His doctor he sees now didn't follow him at birth. His neuropsychologist says we need a letter from a medical doctor. WILL SOMEONE JUST WRITE THE DANG LETTER? This is a boy who is beat down every day he has to try and keep up in a regular classroom. I feel like Shirley Maclaine in Terms of Endearment. I'm taking deep breaths and trusting in God. Peace~
