L – I’d like to add that I’m so sorry this mighty challenge has brought so much pain to your family. It’s sound like you like so many families want to help their children grow to all they can be and the frustration for long awaited answers is so trying!! I’m sure you have been braving this with your family for so long and as you say at great expense. Hopeful one day you will find in your son a Dr Hallwell or the guy who developed Jet Blue airlines (he still struggles with his esteem though brilliant) or just someone who can make it with a much happier satisfying life. Prayers for your family!
