You might talk to your doctor about having respiratory function tests done. That might define the degree of damage done to your lungs. Then, a letter from your doctor documenting that you are not on oxygen and able to exercise at XXX level might help. (Able to climb x number of steps, walk such and such distance without becoming short of breath, etc.). Last, and most important - stop smoking NOW! There is a medication called Chantix (here in the US) that can help (it attaches itself to the pleasure receptors in your brain that nicotine attaches to, meant to be taken for about 3 months.) Failing that, patches, gum, lozenges or whatever can help you stop. Also see if you can find local or even online support to stop smoking. Documentation of all of this might get you in. Just my $0.02 worth as a nurse!
