have recently started having problems with some people at work who are trying to get me to do things that they know doesn't help, when i refuse they make nasty comments like why did they take on someone like you and if it's that bad get it sorted when i try to explain that i have brittle asthma they shut off does anyone have any ideas on how i can either get them to leave me alone or get them to understand the differences between brittle asthma and so called controlled asthma
