Seems like you're doing really well, that's fantastic. But I must say, I feel for you... That nose spray is really, really hateful. I'm 15, and when I was 2, I was diagnosed with asthma (I don't know which degree though) and I spent a few months in the hospital and they had to give me nose drops quite frequently. It was quite a long time ago, but I still remember how dreadful those are! I put up quite a fight with the nurses. But thankfully, that was the last time I've had to use them! Ever since I've been out of the hospital that first time, I've only had to use inhalers and this "Medi-Mist" machine thing that the doctor gave me. It's really odd. But soothing. Well, if it's anxiety that's causing trouble in your case, just avoid stress and relax, I think you should be fine. Hang in there!
By the way, you're more than welcome to e-mail me, or IM me, or whatever, at any time!
