Pemberley - I could have written your post - verbatim. I've used the same words when describing the journey I have taken with my very bright, profoundly dyslexic son, age 14 who we identified in K. It is a roller coaster with twists and turns that include an enormous range of emotions - sadness, fear, anger, pride, hope, etc.
For me, as time goes on, there are longer instances of pride, hope and other positive emotions. I see ds growing and overcoming. Of course, his dyslexia and organizational skills will never go away, and there are times of sadness when I wonder about job opportunities, higher education opportunities etc give his terrible literacy skills.
I've channeled some of my energy in self education (love misunderstood child!) as well as beginning my own special ed training and advocacy practice to help other families. It's been a ride, on balance positive. Not sure of any words of wisdom, other than recognizing that life is not a race, but a journey. Take care, and pace yourself!!
