I recently started work which I haven't done since being diagnosed with emphysema. On my last spirometry my lung age was 73, I am 43. I thought I would be ok going back but I am struggling to breath on my journey there and back and because I have gone back to work I have forgone my benefits I had. I don't know what I can do now as I feel I have made a major mistake by going back to work but if I just leave I won't get any benefits. It's getting me down as I don't know what I can do. Does anyone have any advice?
