I would caution a little against the prevailing wisdom of diagnosis-as-panacea. I've had a diagnosis for most of my life, but never seen stimulants as worth it (admittedly I've not tried them long term, but that's because after reading a whole lot about it I don't want it in my body). I don't think the diagnosis changes anything for me other than that. It's very much a case of "now what". I suppose some people find a great weight lifted from their shoulders at the idea others struggle with the same thing, or that their struggles aren't due to a personal failing. But I can't escape the next step which is that you still have to do go out and do all the same stuff anyway...
