@martybarker,
hey - sorry to hear about this - yeah 42 does seem too young, but kids get it even, so ... you know... it's just bad luck. I have to deal with physical pain on a daily basis and sometimes i get so frustrated and angry about this (I'm several years younger than you) but there is a LOT you can do to help with that - so don't despair. Okay?
i'm sure you are feeling very down right now but it's important that while you read up on your problem, you look after yourself in other ways - eat well and get sleep, that kind of thing- and keep your mind positive it's important - take the fight to it - know what i mean?
You seem like an energetic sort of person and this thing doesn't need to change you - you may need to adapt, but haven't you always been adaptable?
You're gona be okay. Okay?
cheers and good luck
Endy
