You are totally right, but as I said before they can't smell me either, so they don't believe me either. I knew that years before I spoke with them about my problem, that they can't smell me, as expected they wouldn't believe me. But my mother has noticed that my clothes actually smells a lot when ironing the them, and also when going to bath, the bathroom smells. There are more, but I mostly use these arguments to convince her.
So the problem is big getting the doctor to do something, but I got a very good plan right now. In a couple of months I'm going to start to college, and if my teachers notices something (which they will), I will personally talk to them, and the principal together and explain my problem. They would then send my doctor a letter, and hopefully that would make them do something.
This is actually also a tip for the other suffers around here, try that with your boss, teacher etc.
