Thanks everyone for your comments and encouragement. I'll certainly do my best to keep this mindset, though don't get me wrong - every now and then I have a mini melt down about it, then I feel better and get on with things! Dr jonny: you're definitely right that it's the inevitability yet uncertainty of the prognosis that adds salt into the wound of the diagnosis.
In my understanding, it's such a personal condition, affecting everyone so differently (and I've heard and read that it's quite a different condition/prognosis in younger people) so I will just roll with the punches and hope I'm dealt a reasonable hand (as far as reasonable goes!) Golden girl: I hope you're right about a cure; there must be one out there.
Gus: I wouldn't be depressed by you talking about your symptoms. I don't think there's any point in shielding myself from the inevitable. If anything, I think talking to all kinds of people on here and perhaps at a group would help better my understanding of what may (or may not) be to come for me.
Have a nice evening, all :)
