I am s-e and have ms. ms is wildly variable and very unpredicatble. after yearsof good health I am currently ill with it and it could end up meaning i'll miss a deadline. fortunately I know the client isn't wedded to this deadline - and little else rides on it. also the client has missed interim deadlines during the project. however I do wed myself to deadlines and don't miss them. and think it's important.
so - if I do end up missing it do I tell the client the real reason or just keep it vague/say i've had flu? the problem with telling them it's ms is the fear that it will put them off me for life. the fear of saying flu (or just vague "illness") is that they'll think i'm a malingerer. rally can't decide.
