So sorry you are going through something like this, it's frustrating I know. I never wrote a note to my family when they were giving me a hard time about a different health issue, but what I did tell them is that they could come to my next doctors appointment with me and ask all the questions they wanted of the doctor and / or nurses. If you are not up to that, then could always invite them to come here copd.net and search through or even sign up and ask questions, let them know they are more then capable of searching the world wide web to see that you are telling them the truth. Or print off some information to share with each and every one of them. If they don't feel like educating themselves in any of the 4 above forms mentioned above then let them know they have "No Right" to question what you tell them. Sounds little rude I know, but then again how are they treating you? I so hope this matter can be settled soon for you, it is not fun at all nor fair to you this is happening. I so wish you the best.
