Environment is such a big topic when it comes to chronic illness, perhaps an obvious one too but I also think far too many people with chronic health problems get so wrapped up in their own situation that they fall into the trap of imagining all their problems stem from a faulty body. Even when they do realise the environment may be playing a considerable part, they don't seem to see what the issues are or they assume there is nothing that can be done about it, but that's not entirely true...awareness always leads to choices we may have overlooked.
