As not a parent I will not even pretend to relate with what you are going through. But this is one of the most moving and amazing things I have ever read. A book could not contain the details of just how incredible your story is.
Science does work. The confluence of technologies - search, websites,email, computers, bioinformatics, pharmacology, medical technology (and if hirenj's* advice proves useful then forums, it should be at the top), such that someone can identify, diagnose, commision/customize medication and possibly treat a completely new disease in the span of a few years..The future really is here. An ode to the open source technologies and not so open research that made this possible. Of course it is worth pointing out that the skill required to research, evaluate possible leads, try then untry possible treatments, contact and manage communication with the researchers is also not to be underestimated.
