Thank you all for your responses!
First off, I haven't told too many people and it's not because I'm embarrassed I just feel like they may treat me different, more delicately or something if they knew. I tend to push myself way too hard, probably harder than I should if I had MS and people seem to respect me for that and I don't know if telling them would change that. I've been hiking before with these particular people so they know it is something that does not hold me back. One of the girls has hypoglycaemia and she came right out with it and no one winked an eye other than to make sure we had ample sugar for her in case she needed it. The only people I've actually told myself are my mother, one of my grandmothers, my ex girlfriend, and my best friend. Other people know but only through word of mouth(I never told anyone not to tell, I just expect them to use discretion and they have). I've been like MissDee in that I just don't feel the need to tell anyone usually but personally I don't see the harm. I guess it's some kind of twisted pride.
I consider myself extremely lucky in that I don't have any outward signs of MS and the only sign I can always tell is the damage from my ON. Other than that I do sometimes get tired and I am somewhat more forgetful(tip of the tongue thing) than normal.
All considered I think I will tell at least one person but I am, at times, very awkward when it comes to things like this. I guess I'll have to hope they ask if anyone has asthma or something.
freiguy. I'm from Pennsylvania and I'm heading to the Adirondacks to hike Mt. Algonquin and possibly Mt. Marcy starting at avalanche pass. See, that's what I'm talking about pushing myself too hard
