Are we really playing the "oppression olympics" with chronic diseases now? Appalling.
Also as a lifelong asthmatic I've no doubt there are other potentially life threatening chronic illnesses out there, and more to the point there are other chronic illnesses which present much more immediate and wide ranging damage to ongoing quality of life than well controlled asthma does. ALS, cystic fibrosis, Huntingdons and dementia, among no doubt many others, all create much bigger differences to an individuals life than asthma does, even if those conditions are well controlled.
Keeping asthma well controlled also isn't really that bad once you know what your triggers are and can mitigate/avoid them, and keep your blue inhaler on you. Honestly even for me personally my depression and anxiety have a much bigger effect on my life as chronic illnesses than my asthma - and my asthma was really severe when I was younger and I have been hospitalised due to it before, and had to regularly use a nebuliser and variety of inhalers before. Now I just have two.
Also I believe statistically heart disease is a much greater driver of early deaths than asthma.
