I am currently building a character who's background includes a rare seizure disorder. I'd like to stick as close to RAW as possible, so I'm going to use the rules for TLE-x in Augmentation (page 132) for the in game effects of the disease. But it seems to me that there should be a Negative Quality that reflects starting the game with such an affliction. None of the Negative Qualities published thus far seem to take this into account, except for maybe the Borrowed Time, but as silly as it sounds I'd like for my character not to fall over dead at some random moment...
My question is has anyone ever run into this situation before? If so how did you resolve it? How many BP should it be worth to have a disease like TLE (or any other you'd care to discuss)? Any ideas?
