Barbie,
I'm not sure of the protocol in England, but in the US you are legally entitled to copies of all your test results. In fact, when my doctor writes up the blood lab order I tell him to write "cc to Pt" [copy to patient] on it so that I can get my results directly from the lab. Many years ago I did not do this and when I changed doctors I had to pay a small fortune to have all my records copied. Now I like to keep track of it all myself.
One thing I have learned is that you must be proactive in your treatment. That means getting a doctor who understands that you wish to be informed and an active participant in treatment decisions. I've "fired" a couple doctors because they didn't want to bother with this.
Being informed and educated in your disease[s] will go a long way in the success of your treatment.
You mentioned that you want to sleep when you get home. It's possible that this lethargy is due to the inflammation going on. I'll be the first to admit that sleep is a great anesthesia!
Learn to pace yourself. Manage your time, your activites.
Above all, don't let the health providers intimidate you - essentially they work for YOU and have a responsibility to provide you with information and answer your questions.
Again, I'm aware that your universal healthcare works differently, but indifferent behavior from healthcare providers should NEVER be tolerated.
Last but not least, I, too, have asthma, though very mildly. I take Celebrex, max dose, twice daily, with great success.
You take care.
