I dont like the way you try to attack a person that is suffering. I would never say a sick person such a painful thing even if I thought it is true (which I dont in this case). And if I had to I would do it in other way. Too easy to say a sick person "its your fault to be sick and all the things you are doing to cure are making you even more ill, they are the result of the mental disturbances of the sickness itself".
Its the classical shit coming from most of people that havent go trough "chronic conditions". Im surprised to see this attitude from someone that has been or its ill.
