Sorry to hear your trials - some of these people just don't get it and you wish they would come down with MG so they could see how crappy it can be to deal with! They don't realize part of the time how hard it is to make rational decisions and answer in a correct way.
I have found when dealing with some Drs and others that we need to is to just SLOW way down when answering - almost to the point of we are confused and need to think about it - if nothing else it puts the "snappy" ones back on there heals a bit....
Good luck.
I know what you mean about some situations seem to provide some kind of stimulus that makes one feel almost normal for a brief spell - I too have had and the following sweats and the crash effect. I thought it was just me!
