I am so sorry they treat you like that and you have to pretty well lie to them. Educating the public is so important for us MSers and other unseen illness. It is just so much easier for all around. Could you just roll into the kitchen and ask to help at the table doing something to help. Maybe talk about the medicine and how much it is and what it does to a families budget. Maybe some one will get interested in that and look it up on the internet and if they are like me, looking at one thing just makes me look further and learn more. If you had just one person in his family on your side. Good luck
